C.,
I know of 2 options that are different. The first is in Norton at Norton Health and Fitness. They have many different theme parties. They have hip hop parties, fitness parties, and there area few other parties. They do everything from set up to ice cream. The kids really have a great time.
The other options if for girls. There is a place called CheerFactor gym in Foxboro. They have parties with a cheerleading theme. The have a tumble trak and a spring floor. I have been to parties there and they are a blast. They girls really have fun.
Good Luck
