One night bookings

Help!!
How do I stop one night bookings that are starting to pop up? I stipulate 2 nights minimum but i see the single night booking is starting to appear.
If theres an open gap between bookings i block them on my calendar.
Thanks in adavance

Simply put 2 nights as a minimum in your settings.

Thanks Rolf- thats what I do too.
But:
I had another look and in Custom trip lengths there it was, a particular month with one night availability.
I quickly closed that one down.
I found it via:

Calendar, Settings, Availability, Custom Trip Lengths

I’ll keep my eye on that one
