There is a $240 minimum for private parties which includes one craft for eight children. Each additional guest costs $20.
Another option if you don’t need the whole space would be to bring your party to open craft time. Crafts are $10-$20 per child, so this is a cheaper option! They’ll set aside a couple of tables for the group to sit together and you’d have room to bring in snacks/cake/drinks etc. They ask that you bring no more than 8 kids during open crafting, due to the size of the tables.
Parties typically last 2.5 hours with two hours for crafting and 30 minutes for socializing. For your scheduled event, they ask that you please arrive approximately 30 minutes prior to allow for set up, check in, and instruction!
