Our general rule is that waivers are valid for one year. However, for a variety of reasons, this cannot be guaranteed. It's always a good idea to call ahead to confirm your waiver is valid if you have any question. You must have the waiver completed for the Sky Zone park you are visiting (a Sky Zone waiver at one park is not valid at a different park). But don’t worry, you can complete your waiver online before getting to the park.
