I got there are 8:30 on a Saturday. 2nd in line. By 10:00 I think there were maybe 20 people in line. The seats were in the first few rows of the orchestra, to the far sides. I could see everything on the stage perfectly, because the set its compact and everything is pretty far downstage.
We rushed yesterday's (Sunday) matinee. We arrived around 10:45, were third in line, and got first row seats, all the way on the end. By the time the box office opened at noon, there were about 20 people in line.
LOVED THE SHOW!

Rush seats at the Booth are pretty much always front orchestra, extreme sides. Usually they're partial view, but as others have mentioned, they're not so bad for this show because of the way the production is designed.
