  • βž• Extra Participant: $20.00 per additional child (beyond the included 15).
  • πŸ₯· Dedicated Party Host: $50.00 for a staff-led, 45-minute "Mini Ninja Challenge" competition with timing clocks!
  • 🧼 Hassle-Free Cleaning Service: $50.00. Let our staff handle 100% of the cleanup and trash out while you relax.
πŸ’³ Booking, Deposit & Penalty Policies
  • Securing Your Date: A non-refundable $150.00 booking down payment is processed instantly at online checkout to secure your weekend slot. The remaining contract balance is automatically settled using your card on file exactly 7 days prior to your scheduled party date.
  • Strict Time Enforcement: Because our weekend schedules run back-to-back, all parties must clear the facility completely by the end of their designated grace period. Overstaying your slot by even one minute past your 15-minute grace period triggers an automatic $75.00 late-departure penalty fee [πŸ”Ž].
  • The Cleaning Guarantee: Outside food, cake, and juices are welcome! However, hosts are responsible for clearing their trash and wiping down tables. If our Hassle-Free Cleaning Service is declined and the room is left with excessive mess, spills, or cake mush, an automatic $75.00 professional cleaning penalty will be billed directly to your card on file [πŸ”Ž].
  • Waiver Rule: Every person entering the training floorβ€”both participating children and spectating adultsβ€”must have a signed liability waiver completed online prior to arrival.
