Are there life jackets for children at the pools and on the beach at Castaway Cay like there are at the resort pools at Disney World? Also, we have 3 cabins. Two of the cabins got a reservation for the princesses and Frozen at 9:45 and 10:15. The other cabin got the times of 10:00 and 10:30. Can we all wait in line together to get a picture together? If not, can one cabin trade times with the other cabin, number of people being the same? Thank you.
