I haven't found Pop to be any louder than CSR or PO, but we've never stayed in a room by the pools. Pool noise is going to be the same at any resort so I would avoid a pool view room anywhere if you're concerned with noise. We typically ask for lake facing, 60s section, top floor, and we rarely hear anything other than the occasional group walking by or toilet flush early AM. We did hear some construction noise in the morning from the skyliner back in November but we were already up (it was somewhere between 7-8AM when it started I believe).
