50-person film crew, 12-hour days: how many units?
We're scouting locations for a 12-day indie film shoot with a 50-person crew. The days run 12 hours, craft services will be on site, and the ground is uneven grass in a field. The truck access is clear for delivery and service. I know long hours mean heavy use, and I don't want bathroom breaks to cause production delays. Should I stick with standard units for the crew, or would a restroom trailer be worth it for comfort? How many units total, and what's the minimum service frequency to keep things running smoothly?
