Honestly? I like it. It's a new concept in home-haunting, and a lot of the discoveries you make whilst doing this will definitely translate to and inform many of your ideas when you go pro. Also, if you can get your hands on some night-vision equipment (cameras, and whatnot), you have a marvelous opportunity to study the impact or effects of total darkness (or as close to that as you can manage) on various patrons. If you get plenty of people to go thru, representing a good cross-section of the customers you'd get at your pro-haunt, that would give you a very well rounded look at how people respond to this type of stressor.
If you can manage the night-vision technology, and do just that, be sure to report back here your findings. I'm sure it will be be enlightening to all of us (reverse pun intended).
