The walls of the arena's seating area aren't completely straight from stage to entrance region. There's a point on both sides where they narrow, as there are control rooms on the second level of the building and they had to place the stairwells for those somewhere. It'd be backing into a corner, but it'd be better than nothing. Barring that, there's a mezzanine along the back, if the stairs can be reached before the next round of Ow My Spleen Theater goes down.
