Seasickness - These ships are huge and have stabilizers. I get incredibly seasick on small boats, IMAX theaters, carnival rides, winding roads, etc. but I do not get sick on these cruise ships. If you are worried, I suggest booking your cabin low center of the ship where there is the least movement. If you want to take something, take Bonine, but take it before you get on and remember, you should not drink with seasickness medication.
