The two new suggestions are:
- Food trucks, food stands, kids crafts, a petting zoo - get 5,000 together in a fun family event. :) With the help of community volunteers (like LA works)
- Go Big. Do it in a stadium parking lot (probably more obtainable than stadium). Free for those who arrive on foot, bike, or by public trans. Rugs/blankets for picnic style eating. Event provides the food. Music donated.
Arrange tables in a creative fashion so that when photographed from above will make fabulous photos. Fixed Hot air balloon rides allow for these photos?
