Last October we stayed in Ranchos 7B, which surrounds the quiet pool there. The night before we left, the pool was anything BUT quiet. Until midnight. Ranchos was OK, but I would definitely not stay near the "quiet" pool again.
We actually were assigned our requested room in the Cabanas section, but it wasn't going to be ready for several hours. Well, Mr. Impatient here couldn't wait that long. Big mistake. Cabanas would have been perfect, IMHO.
We loved CSR.
