Once you have booked a hotel, never go back and check the price.
I think most of us have heard that before. However, ignore that advice if the company you booked through has a best price guarantee. I have twice now used the guarantee with hotels.com
Have also just tried Accor and they give the price difference plus a further 10% off.
Am I just lucky as I have had no problems or jumping through hoops?Accor is for up to a week after you make the booking.
