Hello: Will be traveling with my family, and a neighbor's family, docking in CocoCay for 7 AM arrival. Kids in the group are all 14 and up. I have a few questions. We'd like to utilize free chairs and the teens would like to visit the water park. Can someone give a rundown on the different beach areas with chairs which would be an option for our group? Can teens 14 and up enter the water park without adults? Thanks.
