camping out? The Hilton across the street. At least, that's what we did for a couple of the bigger XL games during my years (13-17). Not that we even needed to at that point, mind you. But it was still fun to get out there super early before a noon saturday game and just drink in front of the student entrance, under that little cover they have.
Edit: and more advice, from someone who was still always the first one in line during my later years despite the team's downturn: bring friends and booze. can't exactly play drinking games or be super obvious about it, but it helps set the tone for sure. cops and XL employees never gave us any trouble, so long as we kept to ourselves and under the roof/close to the doors.
