I would call them for specifics, but we went on a day that had a $6 "sitting fee" for the whole day and then we paid for what we "painted." They then glazed and fired them, and we picked up the finished pieces 3 days later. I did a big bowl for $16, for example. Each piece has the price on it, so you know what it will cost before you start.
We've seen field trips there - but I do believe you can have parties there!
