Lets look at this from other business perspectives.....
You and your family plan a trip. After researching, and booking the trip, you schedule your vactions away from work. You wife (or any significant other) takes thier vacation. Then, one day the hotel you were booked at says, "sorry, someone offered us more money for your room, we gave it to them." You can't find vacancies at any other area hotel. Your vacation is ruined by the greed of the hotel. Now, you can't give back the vacation days, you have to use them.
Will you have anything positive to say about this hotel? Will you ever book through this hotel again? There is no difference between this and the fling.
