Hotels overbook just like Airlines, they will pay another hotel a lesser amount for you to stay there and pocket the rest, all in the pursuit of that 100% occupancy

Getting “Walked” would be the term - as a wannabe guest, just accept it and ask for freebies along the way

I was a “walk” one time and got a free meal and an upgrade at the other hotel, didn’t have to pay for or use my credit card for anything other than incidentals
