@Roddy4,
The most recent cancellation policy that I am aware of is Firm, and is different from Strict. I know most guests would like all properties to offer Flexible of Moderate cancellations, but that's not feasible for locations that do not have a lot of transient flow due to location and transportation options.
I chose Firm Cancellation for my properties, because it gives us the most time to get another reservation after the free cancellation period ends. If I'd selected Moderate, there is almost no opportunity to get a replacement booking after a short-notice cancellation. The majority of our guests have to get passports, buy airplane or ferry tickets, and if they are unvaccinated get COVID tested 1 day before traveling. Prior to last year, I had a Strict cancellation policy, because I couldn't accept the risk of a short-notice cancellation. I know this policy reduced the pool of guests who would book with us, but at least the ones who did book would be earnest about coming. I participated in the beta for the Firm Cancellation policy, because it is in alignment with cancellation policies on other platforms. I also signed up for the non-refundable rate. We had very few bookings last year due to the local government's COVID regulations regarding which properties could be open, but almost all of them selected the non-refundable option.
