Average Length of Stay (ALOS)

Definition: What does the Average Length of Stay Mean?

Average Length of Stay” (ALOS) is the average number of nights guests spend at a property during a specific period of time. It is used as a measure in the travel and hospitality industries, like hotels and short-term vacation rentals. 

To calculate ALOS, you can follow this simple formula: divide the total number of days guests stayed in the establishment by the total number of guests during that time.

If you manage a hotel and wish to determine your ALOS for the previous month, you need to consider the number of nights guests stayed at your property. For instance, let’s say there were a total of 500 nights. If there were 200 guests during that period, then your ALOS would be 500 divided by 200, which is 2.5 nights.

ALOS plays a vital role in hotel management, as it identifies efficiency and provides insights into how well the property operates. Managing capacity, optimizing guest experiences, and determining the appropriate length of stay for your target audience are a few of the many factors that ALOS can impact.

Remember that ALOS can vary depending on the property type, location, and season. Therefore, it is essential to consider these factors while analyzing your results. Comparing your ALOS to industry benchmarks can also help you understand your performance in relation to others in your sector.
