200-person beer festival: porta potty count for 8 hours?
I'm organizing a downtown beer festival for 200 people next year, running for 8 hours on a Saturday. We'll have multiple food trucks and heavy alcohol consumption (beer and cider). The event is in a city park on grass, with truck access along a paved path about 20 feet away. I'm considering a mix of standard portable toilets and at least one ADA-compliant unit, but I'm unsure about the total count. Should I also look into a restroom trailer for higher capacity? How does the alcohol factor change the math compared to a regular event?
