Used it at least one or two years for a street magic-type show. It's not very big, nowhere near FFL sized. But even then, finding a show that generates enough interest to fill it seems difficult.
Callbacks--or trying to prevent them--proved to be a huge issue. As did the sexual nature of the material. Given that RHPS seems to be on the pop culture downswing*, I doubt UOR shells out the money for it again, especially solely to "plus" AOV. They pay AOV $$ to come up with their own ideas.
* - With Cinemark moving into CityWalk, AFAIK the only venue left doing midnight shows in central Florida is in The Villages. You can't make this stuff up.
