For (some) sold out performances, 2nd Stage sells you a ticket that guarantees you will see the show. They have you hang out in the café, and right before the show begins, they try to seat you if there are available spots. If none are available, you stand in back of the last row. I did this procedure for Dear Evan Hansen back on 5/21/16. I ended up sitting in the first row -- a good deal for me; however, some of the others had to stand.
