Earlier quoted context omitted.
I would assume the reputable but cost-cutting hotels would still be doing a full clean between guest visits, just cutting down on the daily room cleaning while a guest is still there.
Every single hotel or motel should be doing full clean between guest visits, otherwise it should not even be allowed to operate. But if a hotel starts letting people stay weeks without checking their room, they will inevitably end up with hoarders and people that keep food lying around and then comes cockroaches and rats and odors, etc.
The keyword here is "should". I don't have much faith that hotels will actually do this.
