We have rented Naydenov Gymnastics in Vancouver for the past 3 years and have lost track of how many families have followed suit after attending. Coaches are assigned to your group to facilitate and the kids get the run of the gym – zip line, bungi, foam pit, trampolines, the works. Kids love it and it is so much fun that adults get jealous (a few parents at our past events may or may not have been politely asked by Naydenov staff to please remove themselves from the zip line and trampolines :). It also happens to be on the cheaper end of place-rentals. You can either spend 30 minutes in a party room (to serve cake and such) followed by 60 minutes in the gy, or, (LITTLE KNOWN TIP ALERT) skip the party room and spend the whole 90 minutes in the gym. Just tell the desk this is what you want to do when you book the event. Another tip is to request parachute games. Cannot recommend highly enough.
