To me a planb is to have a few hotels, bnbs in ideal locations i can book at reasonable short notice. I know they have space and they are in my budget. I have extra cash so I don’t have to wait for a airbnb refund if they take time. I don’t use other airbnbs as a planb in case something happens with airbnb. A couple of years back we booked a lovely place in normandy, france with indoor pool for feb half term. The owner cancelled while we were on the ferry. Luckily i had a plan b we drove to a lovely chateau near mon st michel and enjoyed our stay. Airbnb did refunded me quickly but not in time to depend on it for checkin at the chateau. I booked a flat in the uk for a colleague to stay while in uk for a few weeks. The host tried to bait and switch i refused and found an alternative airbnb which as it was went ok. I had to wait for a refund because i paid for 3 weeks.
