Our 6 year old DD did this in August and she absolutely loved it. When we came to pick her up she wanted to know if she could go again next year. Let me know if you have any questions about it.
I saw a show on the Travel Channel that showed a Mad Hatter Party with all adults, I think it was like a bachlerette (sp?) party or something, which is what prompted me to look into it for adults only.
