I always do the water parks solo, since my family never has any desire to go there. It's a great place to go solo. The only very minor problems is that I can never ride the family raft ride, since you need at least two or three people in the raft (not exactly sure how many). Also there is a double inner tube ride at one of the water parks, and I can never do that, either. But there are plenty of things to do. I agree that not having a person to watch my stuff is probably the biggest issue - I always get a locker and carry my room card on me. So have fun!!!!
