Gym Parties

Gym Parties are facilitated by a party host or hostess. Basic parties include one hour of assisted activity and one hour in the party room where you enjoy each other’s company. Depending on the package you choose, pizza is supplied! Our deluxe gym party package includes one hour of assisted activities and one hour in the party room where we provide the party products, up to two slices of pizza per child and goody bags.

The Princeton YMCA is a great place for your birthday party! We look forward to helping you celebrate.

Each party reservation is 2 hours long, and is staffed by a host who will assist you with organization and set up. The first hour of the party offers the special activity chosen by you from our options, and the second hour will be free time in our gymnasium or studio for any food, drinks, cake, or activities you may wish to provide. Please note that all refreshments, decorations, and invitations are the responsibility of the celebrating family, and are not provided by the YMCA.

Each birthday child receives a “YMCA BIRTHDAY” t-shirt as a gift!

Sports Party

Offered on Sundays from 2pm-4pm. Choose your favorite sport! We provide a coach for the first hour of your party to run sports and games of your choice!

Splash Party

Offered on Saturdays from 3pm-5pm. Spend your party splashing around our heated indoor pool with all of your friends! First hour of the party will be in the pool. We recommend that your guests arrive about 15 minutes early to get changed if necessary.
