@Tom2542 Whatever settings and policies you have in place at the time a guest books or requests to book is what you have to honor. You could tell the guest that you've changed it and they would have to agree to the new policy, but if they report that to Airbnb, you could be delisted. And Airbnb seems to be handing out refunds, in contravention of the host's policies, like candy these days, so there's not even any guarantee that you'd be paid in full even you did change it.
