Please vote for the best swimming between these 3 resorts. I would appreciate it if you would consider it as seen through the eyes of a 5 yr old and a 9 yr old. Please consider pool theming, slides that a child this age would use (both can swim, neither are strong swimmers), and how crowded the pool normally is. For instance, I've heard the Poly's pool is nicely themed but can be extremely crowded. Thanks!
