I recently booked two different stays a the same hotel a week apart with Priceline.com. When I arrived at the hotel they took an imprint of my credit card and then gave me a receipt when I left. I noticed that the price was different than Priceline (it was cheaper) but I thought it was a further discount from Priceline. When I received my credit card bill, I was charged 246.14 by Priceline for each stay and charged 174.40 by the hotel for each stay. I called Priceline and notified them about the double billing and asked why the hotel was cheaper than the Priceline (guaranteed low price) and was just told that the hotel didn't have the right to charge me. I did receive a credit on my bill but it was for the cheaper hotel charge not the higher Priceline charge. I talked on two different occasions to 4 different employees and on the first call I was told the 71 dollar difference was Priceline's mark-up that they had to make money and I got the lowest price possible. I pointed out that the hotel charged less than Priceline and I wanted a refund for the difference and was told there would be no refund as they had to make money. I did not yell or lose my temper. I then called the hotel to find out what the price would have been if I had booked directly with them. I was told $99 which was the Priceline price that Priceline said you could only get from them, and then when I said I had a AAA card I was told the price would be 80.15. On the second call I asked to talk to a supervisor and was given a customer service rep who told me that Yes they did guarantee the lowest price but since I didn't cancel my reservation before I stayed (and accidentally found out the difference in price) I would not be receiving a refund. I will never use Priceline again and those of you who think you are getting the best price might want to call the hotel you want to stay at and check with them to find out your best deal.
