What's the difference between a room and a guest room? What is the difference between a single room and a bedroom?

Uncleaned room: there is no clean room yet, but it is not necessarily the room that the guest just left.

Check-out room: the room where guests check out.

Take a single room for example: when the front hall is occupied and the housekeeper is empty, it is called jumping room. Reason: There may be guests dodging.

Bedroom: the front hall is vacant, and when the housekeeper checks in, it is called a bedroom. Reason: The main reason is that the front desk did not operate the computer in time when the guests arrived and left the hotel, and did not inform the front desk, which led to the hotel's own use.
