Scaretour seem to have it looking right!
I think that an asylum makeover would be but I think there locations for the mazes are a bit weird.
I also think the the you're next roaming actors would be very good as long as there are many of them.
I can imagine AP night, being quiet, that the roaming actors could persistently stalk the same people.
Anyway I think it's time to have a movie marathon starting with the Blair witch project!
