SAB is the greatest Disney pool by FAR. No pool compares. Sand-bottom pool, complete with sand play area, lazy river, whirlpool, everything possibly imagined.
Next best pool slide wise is BW because it has a roller coaster themed water slide.
AoA has a big pool, but a big pool isn't complete without a cool slide and that is the problem with the Value pools.
CSR is also very cool, with the large mayan pyramid slide and structure, and water-spitting mayan sculptures.
