There's one main pool and quiet pools for each Island (I think for each one). Again, everyone is saying that Martinique is a close one but I didn't think so, but then again we could have been on the far end of Martinique.
The only other resort I've been to is the ASMU. A pool is a pool to me so I can't really compare. There is a water slide and a water fall in the pool. It is not zero entry like some of the other pools. The kiddie pool (if you need it) is very large but not spectacular. But hey, little kids would swim in a puddle and be content, ha! I'm thinking there was a hot tub but it wasn't separate if I remember correctly.
Please make sure you get a map of the place when you check in. The CM didn't give us one so we didn't know such a thing existed until half way through our stay when I saw people with them. We spent that half wandering around trying to find the nearest bus stop. The area around the lake is easy to get around, it's a big circle, but I thought the paths that lead you to the parking lot and bus stops were a maze. We never came out of the same path twice! Ha!
It is a large resort but it has it's advantages and disadvantages. We didn't like walking so far to everything but at the same time since it was so spread out it didn't seem overcrowded (until you got to the busstops on the way back from the parks).
