well I super lucked out there. The folks whose seats I was in got in line around 5pm the night before, i was planning to wait with them but found out Wednesday I had to volunteer Thursday morning. They were like 15th in line. I didn't get in ballroom 20 till about 10am, but luckily one of the dudes I was going to wait with left after the third panel so he let me come up and snag his seat.
