An interesting aside, and way, way off topic...
Back in the old expansion days in the US it was not unusual to rent a bed when you were on the road. It was more like a dormitory than an inn. You were “expected” to share a room with a stranger.
Kind of like the hostel life in some parts of the world today.
So, if the rooms really were all full, that must have been some party.
Boarding houses were a little different.
And my understanding is that families were encouraged to take in a boarding vet after WWII while homes were built. I grasped that from some old time radio shows like Burns & Allen.
There are still some restaurants that have family style seating (you may be sitting next to strangers).
