Frequently Asked Questions

Does Ganbaru Ninja have an age limit for parties?

While there are no age restrictions during birthday parties, we do recommend that the birthday child is turning at least 5. Only guests ages 4-17 are included toward the final headcount.

Is the Guest of Honor included in the headcount?

The birthday celebrant is not included towards the total count, nor are children under 4 and adults 18 and over. Parental supervision is required for guests under the age of 4.

Can adults participate too?

Yes! Anyone entering the course will need a waiver on file. If you have signed one for your child, you have signed one for yourself by default. For example: if Mom completed a waiver for the kids, Dad will still need to complete a separate waiver and select the ‘just me’ option should he choose to enter the course.

When do I need to inform Ganbaru Ninja of my headcount?

If you are below 10 participants, there is no need! Additional attendees above the standard party package can be added up to the start-time as there is no need to be exact with this count prior to the party. We will simply take a headcount as we check-in your group and will adjust accordingly prior to the end of the party. If you are planning on having more than 15 participants, please reach out to us at

Can I bring my own food?

Can I bring decorations?

Yes! If you opt for the "self-serve" party area option you are more than welcome to bring your own decorations. We will provide tables and benches for seating and a table for food.

What is the cancellation/reschedule policy?

Any change or cancellation within 10 days would result in loss of $50 deposit. Please call to discuss any extenuating circumstances that would cause a problem with your party date within 10 days.
