I hate to tell you this, but most likely your guests will contact Airbnb and claim extenuating circumstances and receive a full refund. My guests over Thanksgiving were supposedly coming from multiple states for a family gathering. The reservation was made months ago with a strict cancellation policy. Several days before their scheduled stay they contacted me with several special requests such as early arrival. I agreed to accommodate their requests.
They then changed their minds several times about when/if they were arriving due to weather forecasts in the various areas where they lived. They did not cancel their reservation, but also did not show up at any time during their reserved three night stay. They were scheduled to arrive on Wednesday and check out on Saturday. Several hours after their scheduled CHECK-OUT time they contacted Airbnb to cancel under the extenuating circumstances policy (yes, they asked to cancel a reservation that was completely in the past).
Because they never cancelled their reservation prior to their scheduled arrival or even made a definitive decision about whether they were coming, I was unable to book any other guests into the property.
Airbnb cancelled their reservation and gave them a full refund for dates that were in the past citing the extenuating circumstances policy.
I will be removing this listing from Airbnb as it is in a skiing/winter recreation area where it snows - sometimes every day. The reason guests come to this location is for the snow. I cannot have Airbnb arbitrarily granting guests full refunds whenever guests change their minds or whenever it is snowing somewhere but my home is still fully accessible.
Airbnb only provides about 40% of the bookings on this property and I will be able to fill the majority of those dates through other platforms and through direct bookings and not have to deal with Airbnb's extenuating circumstances policy that is completely unfair to hosts. The few extra bookings I might get though using Airbnb are not worth the financial loss incurred when high season stays such as Thanksgiving are arbitrarily cancelled.
