Minimum-stay rules that protect revenue without killing occupancy

Length-of-stay restrictions solve a real and specific problem. Applied broadly, they create a larger one.

What they are actually for

The problem is the orphan night. You have Friday and Sunday free, Saturday is booked, and nobody can use Friday alone because most leisure guests want two nights. Friday earns nothing not because demand is absent but because the shape of your availability does not match the shape of demand.

A minimum-stay rule prevents you creating that gap: by refusing a Saturday-only booking, you keep Friday and Saturday sellable together.

That is a genuine revenue-management technique with a real payoff on high-demand dates.

Why the blanket version backfires

The rule is only worth applying when there is enough demand to be selective. If you impose a two-night minimum on a Tuesday in a business city in February, you have not protected anything — you have refused the only booking you were going to get.

Every restriction is a filter, and a filter with no demand behind it is just a closed door.

The restriction types, and what each one does

MinLOS (minimum length of stay) — a booking arriving on this date must be at least N nights. The general-purpose tool. Use it on peak dates.

MaxLOS — no longer than N nights. Rare; used to stop a cheap long stay consuming a high-rate period. Occasionally right around an event.

CTA (closed to arrival) — you may not start a stay on this date, but you may stay through it. This is the precise instrument for protecting the night before a peak: nobody can arrive Saturday, but a Friday–Sunday booking passes straight through.

CTD (closed to departure) — you may not end a stay on this date. Protects the night after.

CTA and CTD are much sharper than MinLOS and are consistently underused. They filter exactly the booking that would create the orphan night, without refusing every short booking.

How to apply them properly

By date, never as a default. Restrictions belong on specific dates where demand justifies them: event weekends, peak season Saturdays, public holidays. Your calendar should be mostly unrestricted.

Set them on evidence. Look at your own booking pace for the date. If a Saturday is 80% booked six weeks out, a minimum stay will hold. If it is 30% booked two weeks out, it will not — remove it.

Review as the date approaches. This is the step almost everyone skips, and it is the one that matters most. A restriction set three months out was correct then. Two weeks out, with rooms still unsold, it is costing you money.

Adopt a rule: restrictions come off at a fixed lead time unless demand justifies keeping them. Fourteen days is a reasonable default for most leisure properties. Nothing should be enforcing a minimum stay on a night that is going to be empty.

Vary by room type. Your two suites may justify a minimum stay on a weekend your twenty standard rooms do not.

Keep them consistent across channels. Restrictions that apply on one channel and not another produce exactly the availability gaps they were meant to prevent, and are a common source of accidental oversells.

The arithmetic

Before setting a two-night minimum on a date, ask what it is actually worth.

Refusing a one-night booking is only correct if the probability of selling both nights, times the two-night revenue, exceeds the one-night revenue you are certain of. On a date at 85% occupancy six weeks out, that is easily true. On a date at 40% occupancy two weeks out, it is clearly false.

Rough guidance many properties use: keep the restriction while the date is pacing well ahead of the same point last year; drop it as soon as it is not.

The specific case worth handling separately

The gap you already have — Friday free, Saturday sold, Sunday free — is not solved by a restriction. It is solved by pricing the orphan night to move. A discounted one-night rate on that Friday earns more than an empty room, and it is the one situation where a targeted single-night discount is unambiguously correct.

Some properties go further and surface these deliberately as last-minute one-night offers. That converts your worst inventory into revenue rather than leaving it as a hole in the calendar.

What guests experience

Worth remembering: restrictions are invisible until they block someone. A guest who cannot book their dates does not see an explanation — they see no availability, and they go elsewhere and do not come back to check.

That asymmetry is why the default should be open, and every restriction should have a reason and a removal date.
