When I rushed this show, it was one year ago and it was when the box office opened. The rush was also Tuesday-Thursday only. I heard it has changed and it is every day now. When I did it, they sold front row seats. I actually didn't like front row because the stage was too high to enjoy anything.
I am sure the rush has changed a lot since then. My suggestion would be go to the box office at 10 (or 12 on Sundays) and see if you can get anything, and if they tell you it is two hours before the show, go then. The rush for this show is apparently not difficult at all. I also think the seats are more varied this time.
