Yes. When a guest picks dates shorter than the minimum stay, the booking calendar shows a message that the home requires an N-night minimum, and the guest cannot continue.
How it works. Minimum-night rules live in your PMS and flow to the website automatically. HomeRunner reads the minimum stay for each date from your PMS calendar and enforces it in the booking calendar. Per-date minimums, for example a longer minimum over a holiday period, are honored the same way as the listing-wide default.
Changing the rule. Edit the minimum nights in your PMS. In Guesty, you can set this on the listing, or on the calendar for specific dates. The website picks up the change on the next calendar sync, with no change needed on the site.
