It may be true if you have a large family and stay for a while. A 4-5 bedroom house would be a lot cheaper (and more convenient) than 4-5 hotel rooms.

Of course, large families are the exception not the rule nowadays.

Personally I don’t have a large family and the inconsistently with Airbnb means we don’t use it often at all.

Where are you traveling that hotel rooms are that expensive!? Up and down the US east coast, there are plenty of perfectly good two-queen-bed rooms for under $100 per night. I recently stayed in downtown Boston in a boutique hotel for $130/night and the surrounding hotels were all under $175/night.
