I bought my ticket at around 11:30a-noon Saturday, and the matinee had no rush left. I was given H-5. Weirdly, though, there seemed to be a lot of empty seats in the two front rows, so not sure why I wasn't put up there? Had a great time in any event.
In front of me, an older woman asked for a ticket to that night's performance, and they sold her a side orchestra in row H, two off the aisle. She was on the other side of the house, but had she said rush, she'd have nearly the same seat for $115 less.
