Short Open Gym Sunday Morning 05/17/2026

Short Open Gym Sunday May 17:

We unknowingly had a double party booking for this Sunday and, rather than forcing either family to cancel at the last minute, we are adjusting our Sunday Open Gym schedule slightly to accommodate both groups.

Sunday Open Gym will still happen, but the session will now run from:
10:00am – 11:15am

If 1 hour and 15 minutes is enough time for your family, we’d love to have you join us for a half-price session.

If you already booked Open Gym, we can either:
• move your reservation to another session, or
• provide a partial refund
