I got there just before 7am and there were people in front of me, and by 730 it was 25 people in line (I didn't count the number of people in front of me but I'd guess at least 9 when I'm thinking of specific people)
There was a girl who had tried the rush for the third time and I have no idea how deep the line itself went, I thought people were exaggerating but there were dozens of people (kind of confused by that but understand the desire to see the show.)
they had 20 tickets per show, at least that's what someone else told me, so I'm not sure if that varies and maybe someone else already mentioned. I wasn't worried about getting tickets and I assumed several people would get the partial view tickets
I will go to the review thread to post but this show was amazing, I finally understand in full why people were raving about this show and this cast.
