Honestly, this is just across the board in hospitality. I could totally see this happening at at any of the three hotels I worked at, and these were Mariott and Hilton properties.
Hospitality is such a toxic industry, the only people who can really survive and thrive in this environment are power-tripping psychos and workaholics.
I could see at a lower flagged hotel, but any full service property is going to have a manager on duty in addition to the rest of the staff. For example extremely unlikely to happen at a full Marriott, but maybe at a Residence Inn
The one full-service property I worked at was a Doubletree...and the only person there at night after 10-11 PM is the night auditor.
Then again, none of these properties were particularly large. That Doubletree I mentioned was just shy of 200 rooms, and the other two hovered around 100.
I once had a reservation to stay at a La Quinta and there was literal poop on the bathroom light switch, the sheets on the neatly made bed were dirty (wrinkled as if slept in, black hair, literal dirt), there was what appeared to be a used tissue on the floor just under the edge of the bed, and the toilet was dirty like it hadn’t been cleaned in months (least of the issues).
They refused to fix the problems, give us a new room, or refund us. It was shocking and I’ll never book with them again.
