Allow attendees to bring in Food and Drink
Reduce the prices of the vendors (According to Wikipedia Vendors sold burritos sold for $10, hotdogs and sandwiches sold for $5, a 10" pizza sold for $12, and 20
US fl oz (590
ml) bottles of water and soda for $4 each) The Vendors paid 500 to sell on site. So I suggest reducing the amount that the Vendors were charged.
More Toilets on site.
Not sure what to do about the Rapes and Violence.
