My two visited these clubs quite often. You get a phone and the club people will call you if your kids are ready to leave. Never had to use it though, because we went to pick them up every time! They were having too much fun! And its very safe. They take your picture when you get on the boat so they use facial recognition to pick up your kids along with your key card AND you have to make up a password to tell them every time. So no worries about someone trying to snatch your kiddos!
While they were in the clubs, we would head up to the oh so quiet adult only deck and chill. So fun! Can I go back now, please?
