Hi Steve,
I just had a guest check out early. The couple booked for 7 nights, and after two informed me that they had found work two hours away (working holiday visa in Australia) and would be checking out on the morning of the fourth day. She sent me a change request which I declined as I need to research the implications of me accepting. I discussed with her, and she subsequently sent me another request to amend the booking. After pouring over information from other hosts in the community, I discovered that had I accepted her request to cancel, this would have bypassed my cancellation policy (moderate), and she would have received a full refund for the remaining 4 nights. I requested that she cancel the booking on her ABB profile, without any input from me, which she did. In such a case, it the sole responsibility of the guest to cancel on their ABB profile (if you want to enforce your cancellation policy), and therefore my cancellation policy kicked in. Warning to hosts, DO NOT ACCEPT REQUESTS TO CHANGE THE BOOKING, as this will bypass your cancellation policy. Simply ask the guest to cancel (without any need for your to accept via a change request). When I investigated this procedure of sending me a request to cancel, I asked the guest if she was aware of my cancellation policy, and she said "yes", and despite this she (in my opinion) attempted to bypass my policy and gain full refund for 4 of her 7 nights booking, with TWO requests to me to accept the changes to the booking (both of which I "declined"). It's holiday season here where I am, and I am now changing my policy from "moderate" to "strict".
