"Landing style" describes how each ship gets guests ashore, not whether the trip is good. IAATO caps any single shore party at 100 people. Below that line, everyone lands together; above it, the group splits and the second half waits for the first to return. At 200 or more passengers, part of the day becomes a Zodiac cruise past the coastline rather than a landing. Read the full arithmetic below.
How the score is built
Every operator above is scored on four weighted factors: shore time per passenger (35%), traveller ratings (30%), price and inclusions (20%), and expedition depth (15%). The first two are measured from public data — fleet capacity, IAATO limits, and aggregated ratings from Cruise Critic and TripAdvisor. The last two — price/value and expedition depth — are editorial judgements, scored by this site's editorial team and explained per operator on the methodology page. That is stated plainly rather than hidden, because a ranking that hides its subjective inputs is less trustworthy than one that labels them.
The order above is computed, not assigned: change the underlying capacity, rating or price data and the order changes with it. See the full methodology for the formula, worked examples, and the reasoning behind every editorial score.
The ten operators, ranked
Below is a 150–250 word overview of each operator, in the order the score computes. Full brand-level detail, fleet history and non-Antarctic destinations live on each operator's own page — this is the comparison view.
Poseidon Expeditions Reviews
Rank 1 · Score 86.2Poseidon Expeditions operates a single ship in Antarctica, the M/V Sea Spirit, rated 1D ice class by Lloyd's Register and capped at 114 passengers. The operator has been an IAATO member since 2011, and an AECO member for its Arctic sailings. Per Poseidon's own materials, all 114 guests explore ashore together on every landing: while up to 100 are at the landing site itself (IAATO's per-site limit), the rest are already out by Zodiac or kayak nearby — nobody waits aboard. Up to 3 landings run per day, each around 2.5 hours.
Fleet: M/V Sea Spirit, 114 berths, ice class 1D.
Traveller rating: 4.7–4.8 (Cruise Critic / TripAdvisor)
Reviewers repeatedly single out the expedition guides for their command of polar wildlife, geology and history, often naming individual staff as a highlight of the trip.
Cruise Critic / TripAdvisorThe Sea Spirit is described as small and sturdy for its size, but several reviewers note the converted former research vessel is showing its age, particularly in cabin bathrooms, despite annual refurbishment.
Cruise CriticA recurring note is that pre-trip contact is minimal — some travellers wanted more advance detail on excursion length and more notice when weather forced itinerary changes.
TripAdvisorThe ship's small size is consistently credited with fast, frequent Zodiac landings and closer wildlife encounters than larger vessels can offer.
Cruise CriticOne ship against fleets of three to five elsewhere in this ranking means no helicopter operations, no submersible, and a single itinerary template — expedition depth scores 80, well behind Lindblad's 92 and Ponant's 95. Price/value scores 75, cheaper on average than Ponant, Silversea and Scenic, but pricier than Oceanwide. Suits travellers who want the smallest, fastest-landing ship in the ranking and are comfortable with one vessel and one route family; does not suit travellers who want helicopter or submersible access, or a large choice of itineraries from one operator. Official site: poseidonexpeditions.com. Full profile: Poseidon Expeditions review.
Aurora Expeditions Reviews
Rank 2 · Score 79.8Aurora Expeditions operates three Polar Class 6 vessels — Greg Mortimer and Sylvia Earle, both 132 passengers, and Douglas Mawson at 154. All three use the X-Bow hull design, which reduces pitching in the Drake Passage — the same hull design used on Lindblad's National Geographic Endurance and National Geographic Resolution, so it is not exclusive to Aurora. An IAATO member since 1991. Capacity sits just above the 100-guest shore limit, so landings run as a short rotation — the second group's wait is brief relative to larger ships further down this ranking.
Fleet: Greg Mortimer 132 / Sylvia Earle 132 / Douglas Mawson 154, all Polar Class 6.
Traveller rating: 4.5–4.6 (Cruise Critic / TripAdvisor)
The expedition staff — geologists, historians, ornithologists — are the most consistently praised element on both review platforms, credited with maximising time ashore whenever weather allows.
Cruise Critic / TripAdvisorThe X-Bow hull is repeatedly credited with a smoother ride across the Southern Ocean; a minority of reviewers note limited storage for wet expedition gear.
Cruise Critic / TripAdvisorA recurring complaint concerns pre-departure and in-voyage communication — itinerary or activity details not matching what was sold — and slow handling of refunds when a voyage was disrupted.
Cruise Critic / TripAdvisorItineraries are described as packed with Zodiac cruises and shore landings, with the crew pushing to get guests ashore even in difficult weather; a few reviewers found logistics rushed at busier sites.
Cruise Critic / TripAdvisorPrice/value scores 78 — mid-range, with the parka included and a wide activity menu (kayaking, snorkelling) available at extra cost. Expedition depth scores 78: the X-Bow hull helps in rough seas (shared with Lindblad's newest ships, not unique to Aurora), but there are no helicopters and the activity roster, while broad, is not deeper than Quark's. Suits travellers who want a short rotation without Poseidon's single-ship limitation, and value hull comfort in rough seas; does not suit travellers sensitive to communication lapses around bookings and refunds. Official site: aurora-expeditions.com. Full profile: Aurora Expeditions review.
Oceanwide Expeditions Reviews
Rank 3 · Score 78.8Oceanwide Expeditions runs the most varied fleet in this ranking: the 174-berth Hondius (Polar Class 6), the 123-berth Ortelius (Ice Class 1A), the 116-berth Plancius (Ice Class 1D), and the 33-berth sailing vessel Rembrandt van Rijn, which carries no ice classification. An IAATO member since 1996 — the longest membership of any operator in this ranking. Landing style varies by ship: no rotation at all on the 33-berth sailing vessel, short rotation on Plancius and Ortelius, full rotation on the larger Hondius.
Rembrandt van Rijn is excluded from Oceanwide's effective-capacity average: a 33-berth sailing vessel with no ice class is a different product at a different price, and folding it into a fleet mean with three motor expedition ships was methodologically indefensible — it had handed Oceanwide the highest shore-time score in this entire ranking (90.1), ahead of Poseidon. Averaged across the three ice-classed motor vessels only, effective capacity is 137.7 and shore time scores 72.6. Full reasoning on methodology.
Fleet: Hondius 174 / Ortelius 123 / Plancius 116 (motor vessels averaged) / Rembrandt van Rijn 33 (sailing vessel, excluded from the average).
Traveller rating: 4.0–4.3 (Cruise Critic / TripAdvisor)
With small passenger counts across most of the fleet, travellers describe getting to know individual guides well and consistently value their biology and polar-science background.
Cruise Critic / TripAdvisorCabins on Hondius are called clean and comfortable, with higher-tier rooms singled out as genuinely attractive; entry-level cabins are described as more functional than luxurious.
Cruise CriticOpinions split: many call the food fresh and better than expected for a remote expedition ship, while others describe a narrow one-hour dining window that leads to long lines and, occasionally, dishes running out.
Cruise Critic / TripAdvisorMost landings are described as safe and well organised, but a minority of reviewers report excursions running longer or more strenuous than advertised, which matters for older travellers in particular.
Cruise Critic / TripAdvisorNo parka included and simpler interiors than the luxury tier explain a price/value score of 90 — the highest editorial price/value score of any operator that actually lands passengers. Expedition depth scores 70: strong tradition and route variety, but service and finish are noticeably plainer than the premium end of this ranking. Suits budget-conscious travellers prioritising shore time over shipboard comfort, or those drawn to the sailing-vessel format; does not suit travellers expecting all-inclusive luxury service. Official site: oceanwide-expeditions.com. Full profile: Oceanwide Expeditions review.
Lindblad Expeditions Reviews
Rank 4 · Score 77.7Lindblad Expeditions operates three Antarctic ships: National Geographic Endurance (Polar Class 5, 126 passengers) and National Geographic Resolution (Polar Class 5, 138 passengers per Lindblad's own current ship page), both built with the same X-Bow hull used on Aurora's fleet, and National Geographic Explorer (1A Super, 148 passengers). An IAATO member since 1991. All three exceed the 100-guest shore limit, so group rotation applies fleet-wide.
Fleet: NG Endurance 126 / NG Resolution 138 / NG Explorer 148, Polar Class 5 and 1A Super.
Traveller rating: 4.4 (256 Cruise Critic reviews)
Recurring complaints centre on booking mishandling — cabins reassigned at a forced upcharge, misrepresented "business class" air that turned out to be economy or partial premium economy.
Cruise CriticNaturalists and expedition guides are repeatedly named as the highlight of the trip, sometimes explicitly credited with "making" the voyage.
Cruise CriticThe newer ships are described as beautifully appointed and hotel-like, with a near 1:1 crew-to-passenger ratio frequently cited as evidence of service quality.
Cruise CriticZodiac and shore-landing logistics are a practical strength; itinerary flexibility driven by the Expedition Leader and weather is noted as variable but well-managed.
Cruise CriticPrice/value scores 60 — one of the priciest operators in this ranking, reflecting the National Geographic partnership premium. Expedition depth scores 92, second only to Ponant's 95: full-time National Geographic naturalists and photography instructors on every sailing. Criticism concentrates on pre-departure administration rather than the voyage itself — see the full Lindblad Expeditions review for the complaint pattern, the rating snapshot across every platform this site could verify, and the rest of Lindblad's fleet and destinations beyond Antarctica. Suits travellers who prioritise naturalist and photography depth; does not suit travellers for whom price/value is the deciding factor. Official site: expeditions.com.
Quark Expeditions Reviews
Rank 5 · Score 72.6Quark Expeditions runs the largest fleet in this ranking: Ultramarine (199 passengers, Polar Class 6, two helicopters), World Explorer (176), Ocean Explorer (138), and World Voyager (172). An IAATO member since 1991. Every ship exceeds the 100-guest limit, so group rotation applies fleet-wide; Ultramarine's helicopters offset some of the lost shore time by reaching sites Zodiacs cannot.
Fleet: Ultramarine 199 / World Explorer 176 / Ocean Explorer 138 / World Voyager 172.
Traveller rating: 4.3–4.5 (Cruise Critic / TripAdvisor)
Lecture and expedition staff across Ultramarine and World Explorer are consistently rated a highlight, described as knowledgeable in glaciology, ornithology and polar history and able to pitch talks to a general audience.
Cruise CriticReviewers note efficient Zodiac operations even with full 180-passenger loads, and several call out helicopter-supported landings on Ultramarine as a standout differentiator.
Cruise CriticA recurring complaint concerns thin updates during weather delays, and at least one account describes a cabin reassignment made without prior notice — feedback Quark has publicly acknowledged and said it would address.
TripAdvisorCabins across the fleet are described as unusually spacious for the category, with some suites offering heated bathroom floors and public spaces well laid out for wildlife viewing.
Cruise CriticPrice/value scores 65 — mid-to-high, and helicopter-inclusive sailings on Ultramarine push toward the top of the range. Expedition depth scores 85: two helicopters, the widest route choice in the ranking including Polar Circle crossings, and a large Zodiac fleet. Suits travellers who want helicopter access without Scenic's or Silversea's price ceiling; does not suit travellers who found the communication complaints above a dealbreaker. Official site: quarkexpeditions.com. Full profile: Quark Expeditions review.
Scenic Antarctica Cruise Reviews
Rank 6 · Score 66.4Scenic Luxury Cruises & Tours operates Scenic Eclipse I and Scenic Eclipse II, 228 berths each but capped at 200 in Antarctic waters, Polar Class 6. An IAATO member since 2018 — the most recent membership date in this ranking. Both carry helicopters and a submersible. Landings run as group rotation in shifts of up to 100.
Fleet: Scenic Eclipse I / II, 228 berths (Antarctic limit 200), Polar Class 6.
Traveller rating: 4.6–4.7 (Cruise Critic / TripAdvisor)
Helicopters, submersible, azipod propulsion and stabiliser technology are repeatedly called unmatched among luxury expedition ships; a subset of reviewers describe the interior decor as dated next to newer competitors.
Cruise CriticFood and drink selection is one of the most consistently praised elements of the onboard experience.
Cruise CriticAt least one reviewer argued the marketed premium positioning overstated the delivered experience, citing weak customer-service responsiveness; separate trip reports describe charter-flight and onboard operational issues on specific voyages.
TripAdvisorSome reviewers note the shore-excursion programme doesn't always make full use of the ship's exploration hardware, leaving a gap between onboard capability and what actually happens ashore.
Cruise CriticPrice/value scores 45 — near all-inclusive (drinks, gratuities, butler service), but the $20,000 entry point is the second-highest floor in this ranking. Expedition depth scores 80: exceptional hardware, but the programme is subordinate to a luxury-service model rather than built expedition-first. Suits travellers who want luxury service with expedition equipment as an amenity rather than the main focus; does not suit travellers for whom shore time per dollar is the priority. Official site: scenic.com. Full profile: Scenic review.
Ponant Antarctica Reviews
Rank 7 · Score 66.2Ponant's Le Commandant Charcot is the only Polar Class 2 icebreaker in the world's tourism fleet, carrying 245 passengers into the Weddell Sea — waters no other operator in this ranking reaches. Its sister ships Le Boréal and Le Lyrial carry 264 each, capped at 200 in Antarctic waters, Ice Class 1C. An IAATO member since 2005. All three require group rotation.
Fleet: Le Commandant Charcot 245 (PC2) / Le Boréal & Le Lyrial 264 each (Antarctic limit 200, Ice Class 1C).
Traveller rating: 4.5–4.6 (Cruise Critic / TripAdvisor)
Expedition and hotel staff are repeatedly praised across multiple Charcot voyage write-ups.
Cruise CriticThe ship is described as chic and yacht-like, with every cabin having a balcony; the icebreaking hull is credited with making the Drake Passage crossing noticeably smoother than on non-icebreaking ships.
Cruise CriticNon-French-speaking guests report friction from an onboard environment weighted toward French — some in-cabin content is offered only in French despite English translation elsewhere.
Cruise CriticItinerary fulfilment is inconsistent between voyages — at least one reviewer reported missing a promoted Emperor penguin colony landing, with weather and ice conditions cited as the cause.
Cruise CriticPrice/value scores 42 — Charcot's Weddell Sea programme is among the most expensive in this ranking. Expedition depth scores 95, the highest in the ranking: no other operator here reaches the Weddell Sea, and the onboard science labs are unique to Ponant. Suits travellers for whom Weddell Sea access and icebreaking capability outweigh cost and an English-secondary onboard environment; does not suit budget-focused travellers or those who need English-language programming throughout. Official site: ponant.com. Full profile: Ponant review.
Silversea Cruises Expeditions Reviews
Rank 8 · Score 61.5Silversea's Silver Endeavour carries 220 berths, capped at 200 in Antarctica, Polar Class 6. Silver Cloud and Silver Wind carry 254 each, capped at 240. An IAATO member since 2008. All three require group rotation, and the 240-guest cap on Cloud and Wind means more shifts per landing than any other premium operator in this ranking.
Fleet: Silver Endeavour 220 (limit 200) / Silver Cloud & Silver Wind 254 each (limit 240).
Traveller rating: 4.5–4.6 (Cruise Critic / TripAdvisor)
Near-universal praise for cabin quality — spacious suites, walk-in closets, and attentive butler service, with several reviewers calling the comfort level close to unmatched in this category.
Cruise CriticNamed expedition directors and naturalists are consistently praised for knowledge and enthusiasm, including reaching latitudes south of the Antarctic Circle.
Cruise CriticA recurring and serious complaint cluster spans multiple independent sailings: itinerary changes and weather delays costing one to two days of the voyage, and in at least one case guests never reaching Antarctica at all while other ships sailed the same day.
Cruise CriticMost reviews rate the food very highly, but a minority describe it as merely acceptable given the luxury price point — an inconsistency worth flagging rather than smoothing over.
Cruise CriticPrice/value scores 40 — the widest price spread and the highest ceiling in this ranking at $50,000, though charter flights are included. Expedition depth scores 72: strong naturalist programme, but a luxury-first design rather than an expedition-first one. Suits travellers prioritising cabin comfort who can absorb the cost of itinerary disruption; does not suit travellers for whom reaching Antarctica reliably is non-negotiable, given the recurring landing-disruption pattern above. Official site: silversea.com. Full profile: Silversea review.
Hurtigruten Antarctica Reviews (HX)
Rank 9 · Score 56.0HX operates two hybrid-powered 500-passenger ships in Antarctica, MS Roald Amundsen and MS Fridtjof Nansen, both Polar Class 6. An IAATO member since 2002. At 500 passengers, HX runs the longest, multi-stage landing rotation of any operator in this ranking that still lands passengers at all — well above Silversea's or Scenic's shift count.
Fleet: MS Roald Amundsen 500 / MS Fridtjof Nansen 500, Polar Class 6, hybrid power.
Traveller rating: 4.0–4.3 (Cruise Critic / TripAdvisor)
Science-focused expedition staff delivering multiple daily landings and lectures are strongly and repeatedly praised, with named expedition leaders singled out favourably.
Cruise CriticFull-height windows for wildlife viewing and spacious, well-appointed cabins with good storage are consistently praised, including in otherwise critical reviews.
Cruise CriticA detailed, highly-rated negative review describes charter-flight logistics between Buenos Aires and Ushuaia going wrong on both legs of one voyage, including a rerouted return itinerary guests weren't told about until already onboard.
Cruise CriticOpinions split sharply: several reviewers call it the best value in the expedition-cruise category, while others dispute the "premium" marketing given the flight-logistics failures above.
Cruise CriticPrice/value scores 72 — an accessible entry point for a ship of this class, achieved specifically through higher capacity. Expedition depth scores 65: hybrid power and an onboard science centre are genuine assets, but 500 passengers means the least shore time of any operator that lands passengers at all in this ranking. Suits travellers prioritising price over shore time and comfortable with a longer landing wait; does not suit travellers for whom maximising time ashore is the deciding factor — see Block 7 below. Official site: hurtigruten.com. Full profile: HX review.
Holland America Antarctica Cruise Review
Rank 10 · Score 44.8Holland America's Oosterdam and Zuiderdam carry roughly 1,964 passengers each — no ice classification, and no landing capability. Under the Antarctic Treaty System's large-vessel restriction, ships carrying more than 500 passengers do not land passengers in Antarctica at all. Holland America's Antarctic product is scenic cruising along the coast only: this site states no position on the operator's IAATO membership status, since that detail is not published and should not be guessed at.
Fleet: Oosterdam / Zuiderdam, ~1,964 berths each, no ice class, no landings.
Traveller rating: 3.5–4.0 (Cruise Critic / TripAdvisor)
Onboard lecture programming about Antarctica and South America is consistently praised, even by reviewers disappointed by other parts of the trip.
Cruise CriticReviewers split on the scenic-cruising format: some are content watching penguins, whales and glaciers from the balcony, while others feel the absence of any landing undercuts the "Antarctica" promise.
Cruise Critic / TripAdvisorMultiple reviewers describe the ship as aging for a bucket-list itinerary — cabins lacking drawers, bathtubs instead of showers, and dated fittings, with at least one calling it the worst cruise experience they'd had.
Cruise CriticDining-room meals are rated positively, but the main buffet draws recurring complaints about inconsistency and long lines.
Cruise CriticPrice/value scores 100 — the lowest absolute price in this ranking by a wide margin, for a categorically different product. Expedition depth scores 15: no landings, no Zodiacs, no expedition staff role beyond lecturing. This is a coherent product for a traveller who wants to see Antarctica from a comfortable, familiar large-ship experience without the physical demands of small-ship landings — it should not be judged against expedition operators on the same terms, and this ranking places it tenth specifically because it does not land passengers, not because the ship itself is disqualified from being a reasonable choice for the right buyer. Official site: hollandamerica.com. Full profile: Holland America review.
What reviewers consistently praise and consistently complain about
Read across all ten operators, the same patterns recur regardless of price tier. Organising by category rather than by company is more useful than restating each operator's card a second time — and it shows which complaints are structural rather than fixable by any one operator trying harder.
Consistently praised
Wildlife encounters. Penguin colonies, whale sightings and close Zodiac approaches to wildlife recur as the single most-cited highlight across every operator.
Expedition team expertise. Naturalists, geologists and expedition leaders are praised on every operator's reviews without exception — this is the most reliably positive theme in the entire dataset.
Zodiac operations. Where landings happen at all, the mechanics of getting guests ashore and back are rated highly across operators, even when the wait to get a turn is the complaint.
Consistently complained about
Drake Passage seasickness. Rough crossings are a recurring theme regardless of hull design, though X-Bow and icebreaker hulls are credited with reducing it.
Waiting for a landing turn. On every ship above 100 passengers, the group not currently ashore is the recurring source of frustration — this is structural, not a service failure (see Block 5 below).
Total cost and single supplement. The gap between advertised fare and final price — flights, single supplement, gratuities where excluded — comes up across nearly every operator's reviews.
Pre-departure communication. Booking mishandling, unannounced cabin changes and unclear flight arrangements recur across operators at every price point, including the most expensive ones — this is the theme least correlated with price.
The single most structural item on this list is waiting for a landing turn: it is a direct function of passenger capacity against the IAATO 100-guest limit and cannot be solved by better service — only by choosing a smaller ship. That is exactly what the next section quantifies.
Ship size and time ashore
IAATO caps any single shore party at 100 people. The consequence follows from arithmetic, not opinion:
- Up to 100 passengers — everyone lands at once, no rotation
- 101–140 — two groups; the second waits for the first to return
- 200+ — three or more shifts, and part of the programme becomes a Zodiac cruise past the coast rather than a landing
- 500+ — under the Antarctic Treaty framework, no landings at all
At equal voyage length, the difference between a 100-passenger ship and a 200-passenger ship is roughly double the time ashore. This site computes that as a shore-time score — 100 ÷ effective Antarctic capacity × 100, capped at 100 — for every operator, and no competitor in this space publishes the equivalent metric.
Ship silhouettes below are drawn to one consistent scale by effective Antarctic capacity, so relative size is directly comparable.

HX (Hurtigruten Expeditions)
Holland America LineFour operators cluster within 16 points of each other on shore time, well ahead of the rest of the field: Poseidon Expeditions (114 passengers, 87.7), Lindblad Expeditions (137.3 effective, 72.8), Oceanwide Expeditions (137.7 effective across its three ice-classed ships, 72.6), and Aurora Expeditions (139 effective, 71.9). None of the four is singled out here as "the" small-ship choice — the numbers above let a reader compare them directly.
Source for the shore-party limit: IAATO. Source for the large-vessel landing restriction: Antarctic Treaty Secretariat.
What an Antarctic voyage actually costs
Published brochure prices in this ranking run from $2,000 (Holland America, no landings) to $50,000 (Silversea, top-end suites). Every figure on this site is per berth, double occupancy, and excludes two costs that apply almost universally:
- Flights to Ushuaia or Punta Arenas — rarely included, and a meaningful add-on from most departure countries
- Single supplement for solo travellers — this site does not have a dollar figure for any operator, and does not publish an estimate
- Gratuities, where not stated as included
- Optional add-ons such as kayaking or camping, and any gear not provided
What's included varies more than the headline price suggests. Scenic and Silversea both include gratuities and premium drinks; Silversea additionally includes charter flights to the embarkation port. Poseidon explicitly excludes gratuities. Most operators loan a parka and boots; Oceanwide does not.
1. Is the single supplement a fixed fee or a percentage of fare? 2. Are gratuities included or expected separately, and roughly how much? 3. What is the cancellation and rebooking policy if weather forces an itinerary change? 4. Is the flight to the embarkation port included, or fully on you to arrange?
This site does not have single-supplement dollar figures or cancellation terms for any operator, and will not estimate them. The four questions above cost nothing to ask and get a direct answer where a published range cannot.
Choosing for mobility and pace
Reviewer profiles on Cruise Critic and TripAdvisor for this category skew heavily toward travellers in their 60s and 70s. None of the ten operators in this ranking publishes per-ship accessibility or family provision, so this site does not attribute any accessibility claim to any operator — that would be a guess dressed up as a fact.
What follows from data this site does hold: group rotation means waiting, sometimes outdoors, between landing turns. Boarding a Zodiac is a physical step down from a moving platform, in wind, onto an inflatable boat. More shifts per landing means longer days on ships with higher capacity. None of that is a criticism of any operator — it is the same IAATO arithmetic from the section above, applied to a different question.
Is there lift access between decks relevant to your cabin and the landing deck? Is physical assistance available boarding a Zodiac from a moving platform? Is there a minimum mobility requirement for shore excursions? Is there a minimum age for the voyage, and are cabins available for three or four sharing?
Frequently asked questions
Are Antarctica cruise reviews reliable?
Only as reliable as the sample behind them. Cruise Critic and Travelstride can disagree by four-tenths of a point on the same operator because their sample sizes differ by a factor of six — this site states which sample it used for every rating and why, rather than picking whichever number looks better.
What do most negative Lindblad Expeditions reviews mention?
Pre-departure administration — booking handling, misrepresented flight class, and marketing promises that didn't match delivery — not the voyage itself. Onboard experience and naturalist quality are consistently rated highly in the same reviews that criticise the office that booked the trip.
Which operators have the best reviews for small groups?
Four operators post shore-time scores above 70 in this ranking: Poseidon Expeditions (114 passengers), Lindblad Expeditions (137.3 effective capacity), Oceanwide Expeditions (137.7 effective across its three ice-classed ships), and Aurora Expeditions (139 effective capacity). See the full ranking table for a direct comparison.
How much does an Antarctica cruise cost?
Published berth prices in this ranking run from $2,000 (Holland America, no landings) to $50,000 (Silversea's top suites), excluding flights to Ushuaia or Punta Arenas and excluding single supplement for solo travellers, which this site does not have a figure for on any operator.
Does ship size really change how much time you spend ashore?
Yes, arithmetically. IAATO caps a shore party at 100 people, so above that threshold guests split into groups and take turns. At equal voyage length, a 100-passenger ship and a 200-passenger ship differ by roughly double the actual time spent ashore.
