We understand that for many childrens birthday parties, siblings and parents of children often come along. During a Full Arcade party (not during public hours) anyone can come up to 50 people. However during a more limited Upstairs Arcade party (during public hours) we lack space to accommodate spectator parents and siblings in the arcade. Thus, anyone attending the party inside the arcade, whether they are just waiting, whether they are playing any of the games, has to pay the entry fee.
