The waterparks have rope drop too. BB is very popular and lots of fun for all ages. I would recommend going at rope drop if possible. Otherwise, you are subject to long lines for some of the best slides. We wear water shoes at both water parks as the cement can get very hot.
However, they have to be removed before you go on most water rides (except in wave pool). Also, consider getting a locker. We usually are able to get a small locker to fit most of our incidentals. No direspect to dansdad but Shark Reef is at TL. He is right though, it is awesome. Love the waterparks. Have fun!
