I've had people book and 2 minutes later cancel and get refunded. I find that somewhat creepy that they now have my address. It would be nice if the guest is only sent the address after the free cancellation period.
P.S I know there is the option for non-refundable tickets for a discount for homes, I am talking about Airbnb Experiences in this instance and that feature of non-refundable tickets hasn't carried over from home rentals to Airbnb Experiences.
