Can we have a Pinata?

We love the idea of pinatas! They can be so much fun! But they can also be dangerous, very messy, and typically result in someone crying because they did not get the same or more candy or prizes as someone else! If you want to have a pinata, we do have a perfect spot for it, but we ask that it has a string to pull, is only filled with candy, and does not need to be batted open. The bat while fun, is also a bit dangerous. We have had some close calls and would rather avoid someone getting hit. So please, no pinatas that need to be hit to break open. We also love the idea of confetti! But please, not at GRIT. A pinata or special birthday popper with confetti is certainly thrilling, but it also creates quite a mess that needs to be cleaned up when your party is over. A confetti pinata gets everywhere and, as such, is subject to a special $150 cleaning charge. Why so much? Because we would rather you didn't:)

It says that you provide paper goods. Does GRIT provide cups, plates, etc.?

GRIT provides all the basics for your party. All party packages come with the following: White Paper Plates and Plastic Cups Red Table Cloths Plastic Spoons, Forks and Knives Juice boxes or Water Bottles for kids We also have on hand: 2 Refrigerators to keep things cold and a freezer if you bring an ice cream cake Cake Knife Bottle Opener Matches Bowls for food and a Drink Tub for wine/beer Please note- Bring your own ice as we don't own an ice machine.

Are there specific places for younger children to play?

GRIT is filled with both foam and wooden obstacles. It is not designed for children under 3. Although we permit younger children in the gym area, parents must watch over them because our coaches must concentrate on providing a fantastic birthday experience and are unable to guarantee the safety of non-participants in the gym area.

I have some kids that are coming that are very young, ages 4 & we have to pay for them?

Any child who participates in the private party activities in the gym will be counted as a "participant.” We understand that siblings may attend a party. If they participate in gym/ party activities, we will consider them part of the party and count them as such.
