Why Ship Size Matters When Visiting Antarctica

Ship size matters more than most first-time planners expect, mainly because of how it affects time on land rather than comfort.

Antarctic tourism rules only let ships with 500 or fewer passengers make landings at all, and cap any single landing site at 100 passengers ashore at once. On a small expedition ship carrying under 200 guests, that cap barely matters and everyone can go ashore in one or two quick groups.

On a larger ship with 300 or more passengers, the same 100-person limit forces landings into three, four, or more rotating groups, so each person's actual time on land shrinks even though the ship spends the same number of hours anchored offshore. A bigger ship may mean a smoother ride and more onboard amenities, but a smaller one almost always means more minutes with your boots actually on Antarctic ground, which, for most travelers, is the whole point of the trip.
