Housekeeping

A cleaning step between one guest leaving and the next arriving. The room board carries a dirty / cleaned status and a mark cleaned action, so a room that has been vacated is not handed straight to somebody else.

Switch: Settings > Hotel > Housekeeping.

Where it appears

Hotel shell: Room Board shows dirty and cleaned alongside free, occupied and due out, with the action on the room tile.

Flow

    A[Guest checks out] --> B[(Room marked dirty)]
    B --> C[Housekeeping works the board]
    C --> D[Mark cleaned]
    D --> E[(Room free to sell)]
    E --> F[Next check-in]

Checkout does not free the room on its own — the cleaning step does, which is the whole point of the board.

Screens

Room Board - every room by status, with the rooms waiting to be made up called out.
Front Desk - a room still to be cleaned is not offered for the next assignment.

Switching off. Warns at save when rooms are still waiting to be made up — the settings page says how many. Off, a room is free the moment the guest checks out.
