Wait.. there are hotels which don't have a door on the bathroom? I have literally never seen that. Is this degeneracy uncommon in the US or have I just gotten lucky?
Nate Barzgate does a good bit on it: https://www.youtube.com/watch?v=kgtgjA_UiAo
I stayed at a super fancy hotel in Napa for a work event that didn't even have a WALL separating off the bathroom it was just a half-partition sheer panel thing.
