When you change a minimum stay or an arrival or departure rule in Guesty, you do not need to make any changes to your website.
Why this works. The HomeRunner booking engine reads nightly rates and stay rules from Guesty and enforces them when a guest picks dates. This includes the per-date minimum stay and the check-in and check-out day rules (dates closed to arrival or departure).
What to do. Set the rule on the listing in Guesty. It reaches your website on the next calendar sync, the same way a rate change does.
When a guest selects a range that breaks a rule, the calendar blocks it and shows which rule stopped it, for example "requires a 6 night minimum" or "Can’t check in on this date".
