Bait and Switch Room Rates
I have booked this hotel several times on line, but this recent incident was a first. I received a confirmed reservation from the Days Inn Hotels on line, four months ahead of my arrival date. The confirmation was for one king bedroom for a promotional rate of 25% off when booking 5 nights at a rate of $51.75USD. Examining my bill upon check out, the hotel had increased my room rate to $63.00 for two nights of my stay. I showed the desk clerk my reservation confirmation with the $51.75 rate quoted. The clerk informed me that the HOTEL MANAGEMENT HAD THE RIGHT TO CHANGE THE RATES AT THEIR DISCRETION. I complained that I had also confirmed the $51.75 rate for the stay when I checked in. A clear case of bait and switch! It took ten minutes of heated discussion with the manager on duty to argue that a confirmed rate means just that - confirmed! I won the argument, and received an immediate adjustment on my bill. 
Two days later, I filed a complaint by phone and email with Days Inn's parent corporation-Wyndham Hotels Customer Care Unit. It's been a month, and I have yet to receive a response.
