I had assumed that the kids would check into the kids club (ages 5-7) and this would be a big room with several activities and the kids would be able to go from activity to activity in the club at their own pace when ever they wanted. But I am getting the impression from reading on one site something called a "Navigator" that the activities are all scheduled at a specific time? Is this true? Do the kids in the club all stay together and do one specific activity? If so, do you have to sign up for these activities? Is there a limited number of spots? Thanks in advance.
