For instance, Red Group might land first on one day, third the next day, last the following days and so on. Ships with 200 pax have the potential to give everyone two landings per day as the ship relocates during lunch. Seabourn Quest stays put the entire day. Another factor is the weather - things change rapidly so while one group might go ashore the rest might not. It's all a matter of luck down there.

A smaller expedition vessel with 100 pax will give you a richer, more immersive experience while a bigger ship will give you more space, more luxury and a smoother ride in the high seas. It's all a matter of choice and compromise. Get great weather I'd choose a small ship; hit bad weather I'd go on a bigger ship. However, when you are ashore it makes no difference what ship you are on.
