I'm not entirely sure I understand what you're suggesting, but I will state that I had an Airbnb host cancel at the tenth (not eleventh) hour before a holiday weekend, and I was surprised until I read the reason for it. Airbnb actually responded quite well. It refunded my money, gave me an Airbnb coupon of $25, and offered to try to help book something. I called an Airbnb representative to talk things over, and I found out that if I couldn't find something in the price range of my original booking amount + the $25 credit, Airbnb would cover a hotel that was even pricier, such as a hotel $40-50 higher. Because it was a last-minute holiday search, I had some concerns, but I wound up booking a place that was cheaper than the original Airbnb, and with the $25 credit that I used weeks later, I actually made off "better" financially. Other Airbnb users may have different experiences, but mine worked out okay.
