The current setup has every pass assigned a spot, so you could arrive at 5:00am or 5:00pm and your spot will still be there. The problem you run into is traffic and police closing roads prior to the game due to heavy foot traffic. Your best bet is to be there late morning if you don't want to be there all day. It still becomes a 12 hour day if you get there at 11:00am. So be prepared for a long day.
