Please see the video below (pleas note that the video is on a loop).
In order to sell gaps within your calendar, you can add a special rate as a gap fill.
Please navigate to Prices > Rates in the menu bar.
Select Add rate and give the rate a name, for example, "Gap Fill".
You can choose the minimum stay for the Gap Fill, but in this case, we are working on a 1-night minimum stay since most of our Gaps are one night.
Choose the period and choose Restriction Strategy as Gap Fill.
(Choosing Gap Fill tells our software that this price is only valid when there is a gap in the calendar).
