Graduation day advice needed...

My son is graduating this Friday. School ceremony in the morning and then stadium ceremony at 7:30PM. Not an option to drive back and forth from the house. So I was thinking tailgate for the day. We will have a 15 with us after the morning ceremony. Looking for advice on parking or if someone has done this how did you do your day? Can't park at his apartment. CAN you get a parking place and throw out a tent? Not grilling, will do that the night before and bring with, tables, lawn chairs. So low key tailgate from a normal game day.

Thanks in advance!
