It's 4 hours of fun just for kids, featuring Halloween-themed crafts, activities & games and lots of playtime in the gym. Dinner is included too! Your child will be in good hands, Gymco's friendly, enthusiastic & experienced staff will make sure everyone has a blast! Reservations are required and space is limited. Our Boo Bash sells out! We recommend that you reserve your spot early. Admission is $34 per child, or $28 for Gymco members, for kids age 3 - 12 (must be independently potty-trained) If you have more than one child ask about our multi-child discount. Questions? Just give us a call at (616) 956-0586, or email officeteam@gymco.com. See for yourself why Gymco's Kids' Night Out events are the most fun, most active in town! We're sorry but this event has been reserved. Please review our calendar for another available date and time. Thank you.
