"My son is a shy child, and since it was his first time, he was very nervous. Both the coach and the staff were incredibly understanding, and my son’s anxiety faded very quickly. He had a wonderful time, and it looks like this will become our new favorite place."

Our coaches will check in all guests and ensure that a waiver has been completed. Once checked in, kids can join the coach on the blue floor for explore time. When the majority of the guests arrive (typically 5 minutes after party start time), or when the party parent is ready to begin, the coaches will begin the games on the blue floor. Blue floor games and activities will take about 70 minutes and the remaining party time will be for food/cake.
