I had a 5 night stay at Westin Lagunamar Cancun a few years ago. The cold water tap in the shower dispensed hot water. The hot water tap dispensed scalding water. Hotel was sold out so they could not assign us to a new room. Repeated attempts by the hotel to fix the problem were only successful on the 4th day. (No idea how anyone ever used that room before.) I was refunded 20K of the 40K SPG points I used to pay for the room.
