We booked with Disney. It was with Don Fosters. Lots of people but just fine. The Sting Rays were really cool. We brought wetsuits to use on this excursion but most people felt that the water temperature was fine. 78 degrees
Castaway Cay: Our family absolutely loved this island. Skip the burgers and hotdogs, the ribs are really yummy. We found the ocean water to be a bit chilly. We had been there in April 2012 and found that to be true, so we brought wetsuits with us to use on the island and on the AquaDuck, too. They were very useful!
