What does "on change" signify in hotel terminology?

In hotel terminology, "on change" indicates that the guest has departed from the room, but the room has not yet been cleaned and made ready for the next occupant. This status is crucial for housekeeping and front desk operations, as it informs staff that while the room is vacated, it requires further attention before it can be reassigned to another guest. Knowing this helps in managing room availability and ensuring that guests are only checked into rooms that are thoroughly cleaned and ready for occupancy.

Understanding this term is essential in the hotel management context, as it directly affects operational efficiency and guest satisfaction. The other options describe different scenarios related to hotel operations but do not accurately reflect the situation denoted by "on change."
