Try this
- Identify the private rooms and belongings before guests arrive, and agree on who will explain the arrangement.
- Provide a usable alternative for shared needs, such as where guests may leave bags, without opening the private room by default.

An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
Tell visitors the arrangement clearly instead of expecting them to infer it.
