This is why I will plan to go to a Club Med thing instead of a cruise. Even with nice weather you spend too much time on a boat in the middle of nowhere.
One exception might be a cruise to Alaska to see the glaciers. I hear that is pretty nice.
Where would you go on a boat like that? If you went to your room and that sucker tipped, you are SOL, but if your not in your room you risk getting your ass thrown overboard.
