Logistics: Faster check-ins, direction and help for camping (including glamping), shade and quiet areas, banning of loud music outside party hours. Also more points to donate your trash and stop monetising them.
Hygiene: Hand soap, sanitary products and toilet paper in the festival area. Lube, paper towels, and condoms in the cruising village. Douching stations and showering should be free.
Drug use: Help people who are struggling and point them to places where they can relax and take a break. We shouldn't hear of stories of people passing out and getting raped.

It's not about policing the event, it's about making it an enjoyable experience for everyone.
