One time a hotel - which I had fully paid for a week earlier - kept badgering us for money throughout our stay. They said that we had been given too low of a rate due to some error. The rate wasn't even low, they were just trying to scam us. Furthermore, they had our booking for 1 week and they chose not to contact us about the issue until we arrived (making it really infeasible to change hotels on such a short notice).
Another time our hotel room was smelling like a sewer and the hotel refused to fix the issue or move us to another room.
Just two examples there. Hotels are generally awful.
