01 / BEFORE ARRIVAL
Plan around the busiest part of the day
A steady flow of people is different from a group needing facilities in a short break. Explain when demand is concentrated, along with the total headcount and length of use.
Show the usable entrance and identify who can provide access. If other suppliers are arriving, explain how their unloading and parking affect the restroom position. Keep that route available after setup, when normal activity resumes.
