Use Room Conditions to mark rooms for special uses like an afternoon sales tour or to complete a room repair. Marking the room does not prevent the front desk from selling it.
Also, if the Rooms Management > Hold Rooms application function is set to Active, you can place rooms on hold for a set period (from 1 to 1440 minutes) or for an unlimited time, depending on the HOLD condition code configuration.
