Hard Rock
"Orlando's largest pool with underwater audio system. The pool is "zero
entry", which means you can walk into the pool vs. stepping down stairs to get in. The slide is 260 feet long, there's sand and a volleyball court next to the pool. There's an extra large chess game, game room, pool table and ping pong table located in the pool area. "
They also offered a "dive in" movie in the pool on weekend. Check to see if they are still offering this.
Portofino

cold plunge, a changing room and is surrounded by cabanas and several lounge chairs.
