What is a Minimum Length of Stay (MLOS)?

Updated 2026-05-27

A Minimum Length of Stay (MLOS) is a booking restriction that requires guests to reserve a property for a specified number of consecutive nights. Property managers and hosts use MLOS rules to optimize occupancy, increase revenue, and reduce operational costs associated with frequent guest turnover, such as cleaning and check-in administration.

These rules can be static (e.g., a 2-night minimum at all times) or dynamic, changing based on seasonality, day of the week, holidays, or local events. Strategically applied, MLOS helps ensure that high-demand periods are filled with longer, more profitable bookings.

How it works

Property managers implement MLOS rules through their Property Management System (PMS) or directly on Online Travel Agencies (OTAs). A base rule, such as a 2-night minimum, is often set as a default.

Property management platforms, like Lodgify, can help vacation rental owners manage specific rules, for instance, increasing the minimum to 3 nights for weekends or 7 nights for major holidays. Advanced strategies involve using MLOS to fill calendar gaps; a 1-night stay might be permitted to book an "orphan day" between two longer reservations, maximizing potential revenue that would otherwise be lost.

Why it matters

Strategically setting a Minimum Length of Stay is crucial for maximizing profitability. By encouraging longer bookings, hosts reduce the frequency of turnovers, which lowers costs for cleaning, supplies, and administration per booking.

This leads to higher net revenue and improved operational efficiency. It also helps filter for guests who may be more invested in caring for the property compared to those staying for just one night, potentially reducing wear and tear.

Examples

  • A ski chalet in Aspen requires a 7-night minimum stay during the Christmas and New Year's holiday week.
  • A beach house in the Outer Banks sets a 3-night minimum for all weekend bookings between Memorial Day and Labor Day.
  • An apartment in Paris has a standard 2-night minimum, but allows a 1-night stay to fill a single "orphan day" between two longer bookings.
  • A property manager uses a dynamic pricing tool to automatically set a 4-night MLOS for a local music festival weekend, then reverts to a 2-night MLOS afterward.

Frequently asked questions

How does setting a minimum stay affect my booking rate?+
A high MLOS can decrease your total number of bookings by excluding guests seeking shorter trips, but it often increases profitability by securing longer, higher-value reservations and reducing turnover costs. Conversely, a low MLOS can attract more bookings but may lead to lower net income due to higher operational expenses. The key is finding a balance based on your market and demand patterns.
Should I use the same MLOS for weekends and weekdays?+
It is generally more effective to set different MLOS rules. Many hosts apply a longer minimum stay for weekends (e.g., 2 or 3 nights) to capture higher-demand periods fully. A shorter minimum (or even 1 night) can be used for weekdays to attract business travelers or fill gaps between longer stays. This dynamic approach helps maximize occupancy and revenue throughout the week.
What is an 'orphan day' and how does MLOS relate to it?+
An orphan day is a single, unbooked night between two confirmed reservations that is difficult to fill because it's shorter than the standard MLOS. For example, a single Wednesday available between two bookings is an orphan day if you have a 2-night minimum. Some systems allow you to automatically relax the MLOS for these specific dates to encourage a 1-night booking and capture otherwise lost revenue.
Can I set different MLOS rules for different times of the year?+
Yes, setting seasonal MLOS rules is a core revenue management strategy. For example, a beach property might enforce a 7-night minimum during the peak summer season but reduce it to a 2-night minimum during the fall and spring shoulder seasons. This allows you to capitalize on high demand with longer stays while remaining flexible during slower periods to attract more bookings.
