The party deck could be accessible for all fans with a ticket but the ticket office could also sell an all inclusive(food and drink), standing room only, party deck pass. Tear down the upper endzone sections, pour a concrete slab all the way back to alley sidewalk. Plenty of room to build covered food, drink, beer concessions similar to the one in the picture above. Could build a high brick concourse wall/entrance gate back near the sidewalk to enclose the area and block out the view of McDonald's.
