The seats are whatever they have left usually, mine were in the first row of the flying circle but I know people who have been somewhere in the orchestra too. If you're planning to go tomorrow the box office opens at noon. You should prob get there by 10 at latest, earlier if you can.
My friend has rushed the show a lot and she's gotten partial view side orchestra, balcony, balcony boxes so it depends on what they have left
Also if you are rushing tomorrow I'd get their extra early because tomorrow is the closing show of the original production. They close tomorrow and resume previews in May
I rushed it today... Got there at 7am and I was the second one in line... but 8am, there were about 10-12 people, and but 8:30, at least 25 people! I got V 27-29 in the orchestra.
