@CeliaT0 As I get a lot of single female guests, and it's a 20 minute walk to town from my place, it occurred to me over a year ago to get emergency contact info from my guests. I did ask a guest if Airbnb asks guest for this info-she said she wasn't sure, checked and said there was a place to fill in that info, but that she hadn't done it, and I suspect many or most guests haven't. Or it may be out-of-date and they neglected to change it.
No guest has balked at me asking for this, and they have said they appreciate the care. I figure if a guest had a serious accident, illness, or simply disappeared, their family would want to be informed ASAP.
