Private Parties are typically reserved for Friday Night, Saturday Afternoons and Sundays. Saturday evenings can be booked when there is not a special event. You can book a party any time online by clicking on the BOOK A PARTY link at the top of the website or by calling/texting the Birthday Hotline @ 201.596.6626.

GRIT is filled with both foam and wooden obstacles. It is not designed for children under 3. While we allow younger children in the gym area they must be supervised by parents as our coaches are focused on delivering a great experience for the birthday and cannot be responsible for insuring a non-participants safety in the gym area.

Any child who participates of the private party activities in the gym will be counted as a "participant". We understand that siblings may attend a party which is great. If they participate in the activities in the gym then we will consider them to be a part of the party and counted as such.

A $250.00* non-refundable deposit is required to reserve a private party. Deposits are applied to the remaining balance at the end of the event. You can book a party any time online by clicking the BOOK A PARTY link at the top of the website or by contacting the GRIT Birthday Hotline at 201.596.6626 (text or call).

This is your private party. We do not have a maximum but recommend no more than ~40= 50 people to keep the party feeling comfortable. If your party grows to larger than 40, we will request that you book an additional 30 minutes ( additional fees apply) as the extra guests slow the pace of the party and clean up.

GRITs provides up to three tables for your guests to eat at plus a serving table, cake table, and a gift table. The three eating tables for the kids are standard rectangular folding 30" by 80" tables.

To ensure you get the time and date you prefer, we would recommend booking your party at least two months before. GRIT is typically booked out a month in advance.

Do the coaches guide the kids through the party? Two GRIT coaches will guide your entire Party. From check-in to clean-up our coaches know how to throw a party that kids love! They will run activities that make everyone, parents included have a fantastic time!

After participants checked in (and we have checked that they have signed the GRIT Waiver) they will be organized by our fantastic coaches into a series of activities in the GRIT Gym which will last approximately an hour. The kids will then take a group picture and then settle down for food and cake. Parties are 1.5 hours in length. You will have your GRIT to yourself during this entire time. We can provide extra time if requested in advance (and no other parties are booked) for an additional fee.

Unfortunately, we cannot pencil in a date without a non-refundable deposit of $250 to hold the spot. However, as soon as you are ready to book, you can reach out on the GRIT Party Hotline at 201.596.6626 (text/call) and we will help you secure your preferred date.

All participants in activities at GRIT must have a waiver signed by their parents. For Birthday Parties we recommend that parents sign waivers for their children on our website in advance so that it will automatically be in our system when they arrive. A signed waiver is required to participate or enter GRIT. Waivers only need to be signed one time. You can find the " Sign the Waiver" at the bottom of the GRIT website. Please note that waivers filled out incompletely will delay your child's time at the party as each waiver will be checked prior to your child being allowed into the GRIT GYM.

We have a set of standard invitations for your party. They are available for $25 for BASH parties and are available for free with Ultimate Parties. GRIT will add your child's name, date, and details. All design changes require an extra fee of $25 per hour for all changes with a minimum of 1 hour.

Yes... as long as they do not participate in the activities run by the coaches.

Extra Participant refers to any child who attends the party and participates in activities run by the coaches. Extra participants will be added to your final bill which we will send you once the party is over.

Nope! Why would we count the Birthday Child? You are here to have fun. Our base package is for " up to 15 participants" PLUS the Birthday Child. A participant is any child who actively is involved in the games and activities run by the coaches. We DO NOT charge for parents, grandparents or friends to stay and watch nor do we charge for babies and toddlers who attend but do not participate. Want to add more participants. No sweat! We are happy to accommodate ( additional fees apply)
