Thanks, Helen. I think I'll wait a little longer to see what happens with the forecast before contacting the guest. However, when I read earlier about the Exenuating Circumstances policy, it sounded like Airbnb would require some sort of proof that inclement weather actually occurred. In this case, I would rather save the guest from a dangerous situation that could occur, not that did occur.
Can you point me to Airbnb's Extenuating Circumstances policy? I couldn't find it this time.
