The problem with that: Its hard to keep people moving inside the Haunted House, unless there's someone to keep them moving through the entire attraction... People (mostly teenagers) love to hang out in those places, disrupting other patrons, messing with the animatronics, and who knows what else!
Seriously, Kings Island has enough trouble with teenagers during haunt, anyway. (Though I wish the employees would stop stereotyping teenagers... One employee in particular acted extremely rudely to me last Haunt, because of my age)
