Has anyone here ever been to Nightmares Fear Factory in Niagara Falls, Canadsa?

Niagara Falls Haunted House Nightmares Fear Factory. Canada's scariest attraction near Clifton Hill

It sounds like it's seriously freaky. CBS even did a feature showing photos of guests totally freaking out during one scene in the house:

If you go on their site, they give you no info on if there's actors in there (I think there are from some of the comments I've read) or if they touch you or if your party gets separated. A couple people have said there's on scare that's psychological and totally messes with your head. I'm morbidly curious but not enough to find out for myself. LOL!
