@Debi6 Hi, you can always send an offer or change a reservation to reflect the min or max of days or guests by first changing your setting accordingly, sending off the changed offer or change, then quickly reverting your settings back to what they were.
For ex. if your min # of nights are to recuperate the amount of preparation work, and a night less wouldn't (which is often why hosts set that up and aren't happy with guests asking for less), then you can still change the days to under your normal minimum but overwrite the automatically calculated amount with what you would want.
