I had my daughter’s third birthday party here at the Upper East Side location… fifty kids running around on mats, tumbling and jumping in the bouncy house. The facilities were incredible. There was so much to do that I didn’t need to hire a face painter, a musician or anything else to make this party absolutely stellar. The kids ranging from 1 to 7 years old had a great time. The staff were friendly and engaging of the kids while on the mats. Off the mats, I supplied the pizza, drinks, cake, etc which worked out okay. My complaint was that I had reserved the place with 50 kids in mind which usually requires extra staff and I felt like the amount of staff they had to help when off the mats was not enough… they weren’t great about handing out pizza and cake/cupcakes and helping the kids find a seat… they didn’t even have enough seats set up for all of the kids that I had reserved for… so, that is why I’m not giving them a perfect score… if they were better with helping the food end of things which is part of their party responsibilities, I would have given a perfect rating. I would book a party here again… it was perfect for this age group and definitely perfect for older kids… well worth the price charged for NYC prices… but book early as they fill every party slot months in advance.
