Thanks. I do think this location is unique. I remember reading that it is the only permanent Ren Faire location so they are able to have the permanent rides and restaurants. They also have permanent bathroom facilities with actual flushing toilets. I don't think they had those 20 years ago when I went.
I couldn't find the source stating it was the only permanent one so I did not include that detail.
I hope you find a quality one near you. I think your family will definitely enjoy it.
