Wow, totally opposite my view. As a family we always want to stay somewhere with a kitchen and a private lounge area - hotel suites are cost prohibitive to this, and a lot less charming.
When finding chalets or cabins/lodges for outdoor trips, Airbnbs are often much better located.
To me it is not so much hotels they need to replace, but a streamlining of booking vacation houses to the point where it is almost as convenient as hotel bookings are, but with vacation house amenities.
