Been to your house a long, long time ago - born and raised in the Quad Cities. I should make it back out there one of these days!
The haunt I was involved with for 4 years is run by an art gallery. They pay a group of lead/core actors who have a specific number of hours they have to commit to. The first year I did as many, if not more, hours than a lead and was unpaid, so the next year, I insisted on being a lead and actually worked less, but got paid. Most people there do it for the love. But they would probably not have so many nights where they're struggling to meet minimum staffing if everyone was paid hourly... IDK. That places owns my heart, but logistical and common sense problems like that are part of why I'm not returning this year.
The corporate haunt I'm testing out this year pays everyone hourly. I'll be getting a higher rate because I auditioned for and earned a more involved role. There are things that make me sad about going corporate, but biweekly pay and well ogranized and enforced break schedules are not on that list.
