Average Daily Rate (ADR):
The average unit revenue paid by visitors for all Sale Nights during a given period.
Average daily rate = Total Unit Revenue / Nights Sold
Occupancy rate reflects how many nights have been sold, while ADR is the average price for which the hotel sold. A high ADR is generally better because it means it earns more money for each night sold. However, if the ADR is too high, the occupancy rate will inevitably drop. Again, the goal is to maximize revenue, not ADR.
This is why we also need to pay attention to RevPAR.
