ALOS

Average Length of Stay. Total room nights divided by total bookings over a period.

ALOS (Average Length of Stay) is total room nights sold divided by total stays in a period. It is a structural metric: a hotel with a higher ALOS spreads the cost of acquisition and turnover (housekeeping, check-in) across more revenue-generating nights. Length-of-stay restrictions are the most direct lever revenue managers use to lift ALOS during high-demand windows.
