I just wanted to update anyone planning to rush for the last few shows. Today was a 2 show day. I arrived at the box office around 8:45 AM and there were about 40 or so people ahead of me. At first, I thought "why even wait," but then I figured maybe a majority of the people in line weren't buying more than one ticket...I mean who is nice enough to wait in line for somebody else for over two hours in 30 degree weather??
There was a LONG line behind by the time the box office opened. It was SRO for rush and I was able to snag the second to last ticket for the evening performance. The afternoon performance sold out probably 30 people into the line. They did seem to have some tickets available at full price, so once they sold out of rush some people stuck around.
I'd honestly say for the rest of the run you probably have to get there closer to 7:30, if not earlier. I know I was gambling by getting there at 8:45, but it was a risk I was willing to take. I wanted to see the show, but only a certain amount of standing outside in the cold in the early morning was do-able for me, especially waiting alone.
