update: I rushed Friday Nov 19 for the 8 PM show and arrived at 7:30 AM- I was third in line, behind two people who arrived together at 6:45 AM. The next person arrived around 8:00 AM, then 8:20, and by 9 AM there were 12 of us in line. By the time the box office opened there were 20 total.
The seats were pretty good- I had row P orchestra right, and others seemed to be similarly placed. The show is staged towards the center so you don't miss too much on the edges, although I'd be interested to see it from the other side.
