MinLOS / MaxLOS (Length-of-Stay Restrictions)

MinLOS (Minimum Length of Stay) and MaxLOS (Maximum Length of Stay) are revenue management restrictions that control how many nights a guest must (or can) book in order to be eligible for a given rate or arrival date.

MinLOS

A MinLOS rule blocks bookings shorter than a specified number of nights. Used to:

  • Protect high-demand dates from being filled with single-night bookings that would block profitable longer stays
  • Increase ALOS during peak periods like New Year's Eve, Saturday nights, or major events
  • Improve operational efficiency by reducing turnover

Example: "MinLOS 3 on New Year's Eve" means a guest arriving on Dec 31 must book at least 3 nights.

MaxLOS

A MaxLOS rule blocks bookings longer than a specified number of nights. Less common than MinLOS, used to:

  • Prevent long stays from blocking inventory during anticipated demand spikes later in the booking window
  • Manage pricing when rates for future dates are higher
