I went a few minutes after 10 today and there were two groups ahead of me so must not have been much of a line. They said rush seats were off to the side and obstructed view but they aren't sure how obstructed since it's the first show. They also had a "flash sale" for $69 for the second row and I think every one there opted for that instead.
At Little Shop today the posters were $150 and Playbills were $40. I am pretty sure the playbill I got has autographs from both Glick and Groff but honestly can't tell for sure.
