What do you mean by the number of room nights

the total number of rooms booked or actually used in a specific period of time.

It is used to measure the hotel occupancy rate, booking situation, and the scale and influence of activities. The number of room nights is obtained by adding the number of rooms booked or actually checked in every day. For example, a hotel has 1 rooms in a certain month, and the number of room nights in that month refers to the sum of all the rooms booked or actually checked in.
