50-person film crew, 14-hour days: how many units?
I'm coordinating a film shoot with a crew of 50 people, working 14-hour days for two weeks. The location is a rural field with firm ground, and a vacuum truck can access the site easily. The crew is mixed gender, and we'll have catering on-site. No alcohol is served, but long hours mean heavy use. I'm considering a mix of standard units for general use and at least one ADA-compliant unit to meet the ADA 5 percent cluster rule. How many total units should I order, and should I upgrade to deluxe flushing units or a restroom trailer for better comfort?
