Rpr has activities so does hard rock. The hard rock tm's were so fun. My ds 8 stayed all afternoon one day and they had scheduled stuff all day long. The hard rock pool is very shallow. i do not think it goes past 4 feet (correct me if im wrong) There are lifejackets for small kiddies that want to go on the slide, just watch though when you get to the bottom it is not that deep, i busted both knees when i landed.
The portofino bays slide area felt deeper to me. There is sand at Port. bay, and hard rock. I cant remember if RP had sand. and no noodles at any.
They also have movie nights where you can swim and hang out at the pool while watching a movie on a big screen.
sorry, i know you didnt ask for all that info, but the pools at each resort are so cool and the tms running it are too.
