I thought so at first too, but the role names we received for Sprung #1 point to Poe being there, not in a Soundstage. Also, keep in mind that the tents are deceptive. They're a lot bigger than you think. Some of the walls in Catacombs last year were quite large. 15 feet at least, I'd say. Meanwhile, we've seen concept art for the Cemetery facade. It's about 20 feet high. Conceivably, it could fit vertically, but Tents never have internal facades because they need all the space they can get inside to make the length of the house up to par with other locations (Soundstages, Parade Building). Thus, the cemetery house must be in Soundstage 22.
As for a casino house, I'm in no way convinced there is one in the first place. The Runes room is in the other tent.
