"I heard that they only sold out rows AA, A,and B out of student rush tickets and that they're giving the rushers rows C and D...not sure if it's true though. Does anyone know for a fact that the rush seats are balc seats?"
Rows B, C, and D are not rush seats..at least not center orch. Those seats aren't "rush seats" ever. Unless you mean the side orchestra box seats? In which case there are only like...maybe 6-8 of those on each side, though I heard those were sold out as well, but that may or may not be true.
I remember back sometime last summer the rush seats had been bought out by a company associated with the show, and when I rushed, I was given row Q on the side, in the orchestra, and others were given rear mezz, and a couple people were given Row A in the balcony. I'm going to assume that they have some seats similar to those that they give out when the seats in rows AA and A are sold out.
