I'm glad you posted this, I kept wondering about this house when I first heard about it, But in HHN you Don' t need this type of house to go in a house by yourself,
You just need to know when to go, there are some times that houses are totally empty, specially late at night near closing time, or if you are first in line when they open,
well, ok about this idea, it could work, but 25 bucks for going to a house once, I don't like it, if the house is really cool, you won't remember it unless you pay more
if the house sucks you're going to be disappointed, the idea i like it for HHN only if they sold a pass with the frequent fear pass so that you could go once every night or something,
