I've got to second the kudos for this pool. It's practically a water park in and of itself. It's big enough and has such lush foliage and plenty of twists and turns that you can easily get lost, so keep a reign on the kiddies!
If you've got a few hours to kill, you can easily do it here and have as much fun as if you went to Typhoon Lagoon or Blizzard Beach!
