My kids, especially my son who was 9 at the time loved the pool party.
We stay at the Poly, so on our pool day I was up at 6 for no reason, did laundry and headed to the pool to get our table for the day (dh doesn't always swim and we like a table for drinks, lunch, dinner). My kids couldn't wait til 1 to start the games. They had multiple breaks and came back for drinks/snacks. They loved that they won prizes too. We could barely hear what was going on as we were on the slide side of the pool so I could see the castle and they were primarily in the low end. Edited to add-we could see them or would walk over if we couldn't because they are our responsibility not the lifeguards/people running the games.
It kept them busy on our pool days because I know they would be bored swimming/going up/down the slide for 12 hours-yes I am psycho, pool days mean we don't leave the pool.
Our next trip my kids will be 17, 15 & 13 and I bed my 15 yo (son) will still want to play.
