Please contact us if you cannot find an answer to your question. We are happy to help!

Eight (8) years is the oldest birthday party that we host at the gym. We are always open to private gym rentals for other groups or family events.

Yes! You may invite children older than 8 years to the party. All guest are included in the attendance numbers. Youth/Adults (13+) are included in the adult count and all others are included in the children count.

We ask that you arrive no earlier than 10 minutes prior to your scheduled party time. If you arrive earlier, you may be asked to wait in the lobby or outside until the party room is ready for you.

We ask that you pay the balance of your party during the last 30-minutes of your party, after all of your guests have arrived and any extra items have been accounted for. We are cashless and the balance must be paid by DEBIT (no cash). We charge a service fee for credit cards.

Domino's Pizza and will come to your party 30-45 minutest after your start time. We do have pizza bags to help keep your pizzas warm. Pizza may not be available for parties starting before 10:30 AM.


If you wish to add anything extra or order more than what is included in the party package when you are making your reservation, please call us.

 YES! You may bring in your own food, drinks, snacks and treats. No nuts or peanuts are allowed. We also do not love fish, eggs, or rice. Fish and eggs smell, and rice sticks easily to socks. Must be peanut/tree nut free. 


If you are having food catered or delivered to Balls of Fun you are responsible to attend to your food delivery, at the front entrance, when your food arrives. 

Our staff (your Party Host) will greet you and your guests and go over the organization for the party. The host will sign in your guests and direct them to the party room and gym areas. The host will make announcements to help with the timing and flow of the party and remind guests when there is 10 minutes left in your party time.  The party host will go over bill payment in the last 30 minutes of your event.


They DO NOT serve the food, drinks or cake because many parties bring additional food. Also, many parents at the party want to help serve their own children, because they may have specific dietary, food and drink preferences or needs. They are also not there to clean up your party room, please be respectful. 


Any decorations or balloons brought for a party must be taken with you after the party. Also, please pop or take any blow balloons.

We clean the gym, eating areas, washrooms, party rooms, and equipment frequently. Our staff have procedures to follow and are there to assist if you notice something. Please avoid coming to the gym if you or your child feel ill. 


If a child is sick at the gym or has a washroom accident, our staff will zone-off the area and are required to wear masks and gloves so they can disinfect and clean. If your child is sick at the gym, you will be asked to leave (no refund). This is to ensure the safety of the other guests and our staff.
