My husband and I just booked our cruise for December 16-23, 2012. We are so excited. We have cruised once before, and this cruise is to all new places. We are so excited we can hardly wait. Visiting nassau bahamas, st thomas, puerto rico, and grand turk. Wondering what kinds of things we could do, that are different than the usual snorkeling, or whatever. Also, who else is cruising with us???
