Average Length of Stay (ALOS)

Reviewed: 2026-10-10 ยท Authority: Scale My Hotel Advisory ยท Verified Standards
PLAIN-ENGLISH DEFINITION

Average Length of Stay (ALOS) measures the mean number of consecutive nights guests spend per confirmed reservation over a designated analysis window.

CALCULATION FORMULA & UNIT MEASURE ALOS = Total Occupied Room Nights / Total Number of Confirmed Bookings

Why It Matters for Independent Operators

Longer stays reduce housekeeping turnover expenses, check-in front desk labour, and transaction charges per guest night. High ALOS creates a more predictable revenue baseline.

Practical Scenario & Calculation

Illustrative Scenario

[Illustrative Scenario] Over a 30-day period, a leisure resort records 300 occupied room nights across 120 separate reservations. ALOS = 300 / 120 = 2.5 nights.

How Operators Can Apply This Concept

Design multi-night packages with progressive discounts (e.g., stay 3 nights, receive complimentary dinner) during shoulder periods to lift mid-week ALOS.

Common Misunderstanding to Avoid

Leisure resort ALOS typically ranges from 2.0 to 4.0 nights, whereas urban business hotel ALOS is often 1.2 to 1.8 nights. Target benchmarks must match property type and destination.
