That would scare the absolute crap out of me. Considering I generally carry weapons on me, I can't imagine that would turn out well for either of us if I was trapped in a room like that guy crouching haha. I'm not sure where this location is, but I'm guessing it's fairly remote which I'm sure makes visitors feel a little more lax with their personal security. That is a pretty brilliant idea though.
Skye, it's clearly fake watching the videos, but I'm sure the costume is much more intimidating in person, especially when you're not expecting it. Being in these places tends to put anyone more on edge than they would be just taking a stroll through the park. Add that to surprise and you get terror. people don't pay attention to details when they're frightened. Another example of that is this video:

All those people are focusing on though is the fact that they're being chased by what looks like a dinosaur lol. I bet you'd be more scared than you think in that situation ;) I'd probably have a damn heart attack, especially if I was exploring alone.
