I just heard of this, and I'm doing it next year for my son's birthday! We're already booked this year. You can go to Home Depot and let them know you want to have a party there. They will let you set up in the special classes room and select a project for the kids to do -build a toolbox, birdhouse -that sort of thing. The woman I talked to said everyone LOVED it -and it's really cool and different! The kids also have a great treat to take home!
We're doing a pool party at the YMCA this year for my oldest. He wanted that -and they're lots of fun if you have one nearby. We're members, but ours lets non-members rent it too for pool parties.
