I don't know if it has been closed in the last couple of years since I stayed at the Poly, but there was also a kiddie water jet play area off to the side of the main pool. It was basically water shooting up in little jets that toddlers loved to play in.
Personally, I didn't care much for it, as it was literally blocked from my view by some shrubbery when I would try to stay in the main pool with one daughter and my other daughter would go play in the kiddie area. I had to step out of the pool to be able to keep my eyes on both of them. Given what happened at the Swan/Dolphin resort recently, I'm even more concerned about being able to watch my DDs at all times.
