Estimate people at the busiest moment
Guests, hosts and helpers may overlap even if an event invitation lists only guests. Describe the duration, programme and existing bathroom access. For a work project, include simultaneous trades and shifts rather than the number of people on one contractor’s list.
Discuss facilities as a combination
Ask how quantity, washing, accessible provision and cleaning support the expected use. Avoid choosing a number from a universal rule that ignores the occasion. A recommendation based on a brief still needs confirmation against the actual property and applicable organiser requirements.
Check who overlaps, not just who was invited
Include hosts, helpers and suppliers when describing the busiest part of the occasion. Explain how long people stay and which permanent facilities they can actually use. Discuss quantities with washing, accessible needs and the service arrangement rather than treating an online headcount rule as a complete recommendation for the property.
- Busiest simultaneous group
- Usable permanent facilities and hours
- Units, washing and support assessed together
