Seeking Pregame Advice for Ravens Game

Hi all. Lifelong fan (63 yrs) but haven't been to the stadium on game day in over 15 years. Son and Daughter in law are taking us to the opener as an anniversary gift and excitement is starting to build ! We have purchased parking at the Yellow Brick lots on Big Tree (south side I believe). Hoping to get there as soon as they open (4 hours before kick off). Any advice on when to arrive (assuming cars start lining up early) and is it better to approach from the west or east? Thanks and Go Bills !!!
