Island activities in the rain?

[psimon]

I realize there is probably much to do at all of the stops on the eastern cruise in the rain. There is lots of shopping available, and touring from a busses / taxis in the rain. Beach activities, however, are proably out.

What happens for the day at Castaway Cay? I am guessing there isn't much to do if you get there and it is raining? Am I wrong? Do they just stay at sea that day if weather reports expect no break?

Has anyone gone through this?
