^^ Mostly all of the Haunted-House type attractions I've been to abide by the "if you don't touch us, we won't touch you" policy. I would assume it's fairly universal, given our high propensity for lawsuits in America. Don't quote me on that though.
As far as the quality of VF's haunted attractions, I haven't been there in a few years but the last time I was there, both the general theming throughout the park, and the mazes were top-notch. And, from what I've heard, it's gotten a lot better. The only minus for me, was the fact that only a couple of the rides were operating at the time I went, Wild thing, and High-roller (maybe Corkscrew), but that's probably subject to frequent change.
If you're already in the area, and assuming you have extra cash to spend, "Spookyworld", which is about 5 miles away is an awesome haunt too, and it takes a good while to see everything. It's called something else now, have to look it up. It's on the Renaissance grounds.
