A two-night gap between bookings often goes empty. A targeted gap-fill discount can convert it into revenue you would otherwise lose.
Every holiday rental operator has them — the one or two-night gaps between longer bookings where the property sits empty. A Saturday-to-Wednesday booking followed by a Friday-to-Monday booking leaves Thursday night empty. A three-night gap appears between bookings in a week you had hoped would be fully booked.
The instinctive response is to set a minimum stay that prevents these gaps from forming — a seven-night minimum in summer, for example. But this approach has its own cost: you lose bookings that would have happily taken four, five, or six nights, simply because you are holding out for the full week that may never arrive.
Gap fill pricing is a more sophisticated approach: dynamically price and market these short gaps to make them attractive to flexible bookers, converting empty nights into incremental revenue.
Not all gaps are worth filling equally. Before deploying any gap-fill strategy, understand your specific economics.
Your minimum profitable rate is what rate per night makes a booking financially worthwhile after cleaning costs, consumables, and utilities. For many properties, this is lower than you might expect: if cleaning is £80 for a changeover and a single-night stay brings £100, you make £20 profit on a night that would otherwise generate nothing at all.
The changeover cost factor: a single-night stay requires the same changeover effort as a week-long stay. If changeover costs are high — expensive professional cleaners, linen hire service — very short stays may be economically marginal and not worth pursuing.
The flexibility of the gap matters too. A two-night gap is much easier to fill than a one-night gap. Three nights or more gives you genuine short-break territory that a broader range of guests will consider.
Gap fill pricing applies an automatic discount to dates that fall in calendar gaps, making them more attractive to last-minute bookers who have flexibility on property and specific dates.
The mechanics: a gap of N nights appears in your calendar between two bookings or between a booking and a blocked period. A pricing rule triggers: if a date creates or fills a gap of two nights or fewer, apply a 20 percent discount. The dates become more competitive in search results and OTA listings, and a flexible, last-minute booker fills the gap.
LetPilot pricing rule engine includes gap fill as a configurable rule type.
Navigate to your property pricing rules. Add a new rule with type Gap Fill. Configure the gap threshold — for example, gaps of one or two nights. Set the discount amount as a percentage or fixed amount. Optionally reduce or remove the minimum stay requirement for gap dates, which is often necessary to make single or two-night stays bookable at all.
The rule fires automatically. You do not need to identify and manually discount gap dates — LetPilot monitors your calendar continuously and applies the pricing logic as gaps appear and disappear with each new booking.
Beyond passive pricing adjustments, LetPilot can send you gap alerts — proactive notifications when profitable gaps appear in your calendar.
A gap alert might read: "3-night gap appearing at [Property Name]: 14-16 March, between existing bookings. Consider promoting this period."
Armed with this information, you can post the dates on social media targeting local or flexible bookers, email past guests who have expressed interest in returning, promote the dates to your newsletter list, or offer the dates to a waiting list of interested guests you maintain.
The alert-driven approach works particularly well for sought-after periods. A three-night gap in peak summer at a popular coastal property is worth actively marketing, not just passively discounting.
Minimum stay rules and gap fill pricing work in tension — your minimum stay rule is what creates the gaps, but it is also what protects your average booking length and nightly rate.
A sophisticated approach uses conditional minimum stay rules: standard booking requires a three-night minimum during peak season; gap exception allows one-night minimum if a single night fills a gap between two existing bookings; last-minute exception allows any stay length at a discounted rate if dates are within 48 hours.
This layered approach maintains your preferred booking profile for standard forward bookings while allowing the flexibility needed to capture revenue that would otherwise be lost in gaps.
Gap fill pricing is most effective when combined with last-minute discounting. Most gap dates are also last-minute dates — they have been available for a while and have not filled. A 15 to 25 percent last-minute discount applied to dates within seven to fourteen days without a booking makes them competitive with OTA last-minute deals.
Configure this as a separate pricing rule: dates within 7 days with no booking apply a 20 percent last-minute discount. The combination of gap-fill positioning and last-minute pricing creates a strong offer for the significant market of flexible, spontaneous travellers.
Your most receptive audience for gap-fill offers is previous guests who had a great stay and would return if the timing and price aligned. A simple, personalised message works well:
"Hi [Name] — we have a last-minute window at [Property] from [dates] that might suit you. We have reduced the rate for this short break. If you are flexible on timing, we would love to welcome you back."
This kind of direct outreach often converts at higher rates than OTA discounting, and it drives direct bookings with no commission cost. In LetPilot, you can filter your past guest list by property and send targeted messages to relevant previous guests directly from the dashboard.
Measure these metrics to understand how well your strategy is working: gap occupancy rate (what percentage of gap-night availability is being booked), revenue per gap night (average nightly rate achieved on gap-fill bookings versus standard bookings), source of gap fill bookings (OTAs, direct site, or past guest outreach), and changeover profitability (are short gap-fill stays generating positive margin after cleaning costs).
A well-tuned gap fill strategy typically adds 5 to 15 percent to annual revenue for properties with frequent short gaps — revenue that would otherwise be completely lost.
