I would compare overall attendance numbers of the other haunts doing Thursday and yours. One theory posed to me has been that the fewer nights run the better so the cast is not worn out. They can only be at the top of their game so many hours and somehow this equates to better word of mouth and more over all customers?
This year we dropped Thursdays. Like it is better to go directly into a busy night and have a better show rather than have to readjust to one from a boring night. If their is a slow night it would be after when the actors are slumping. Or on Sundays their are fewer actors as some might need the day of rest to go to work.
Another fabulous post from the U.S.Department of Wild Imaginings, now in spectaclar stereo, sponsored by the Adhesives and Sealants Council, suggesting ways to stick things together since the 1800s. Not fabulous in a gay way. Your results may vary. Illinois residents add 8% sales tax.
