I went to the 2015 regional with a student SRO ticket. We got to the doors about a half hour before they opened them, so about 2 hours. We got on the glass right off the bottom of the stairs and it was probably the best option if someone had to run to the restroom quick. People were pretty respectful about letting them back to their spots. I did watch the other games from the top riser of the bleachers( i think they are 3 or 4 levels?) and that was a great view as well.
It was a fun atmosphere mixing some students and adults together, fun times and crazy loud!!
