Try this
- Choose an approximate finish and a direct phrase you are comfortable saying to guests.
- Coordinate between hosts so one person does not have to enforce an ending the other keeps extending. Handle transport needs before the last minute where possible.
A worked example
“At nine, we’ll start wrapping up rather than waiting until we’re exhausted.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
Tell guests directly when needed instead of relying on increasingly obscure hints.
