We are a no-chainsaw haunt as well. I have thought about incorporating one into the show, but every time I even mention it one of my creative team screams “NO CHAINSAW!”. And, I’m glad they do. We have avoided it for this long, so it would be sad to ruin the trend.
Endings, of all sorts, can be difficult. I’ve noticed that by the end of most haunts, mine and others, that most patrons are pretty desensitized to most scares. One of the best things you can do is to make them think it is over, so they drop their guard, and then hit them with a scare.
To be honest, we have been hit and miss in the ending department the last few years. We’ve had a narrow cave passage at the end of our haunt for the past two years. That has limited our options on scares. This year we are transforming the end into a larger room where we can put on a little more of a show. I think that will help, but if we can’t scare them at least we will entertain them.
