This price guarantee thing is a SCAM. I just booked a hotel room at ramada.com last night and found a better deal on another website.
At first, the Ramada representative sent me an email indicating that they can find the rate but couldn't book it. I went back and tried and I was able to get to to the point I've to enter the credit card info. I emailed back and indicating that at which point did the reservation not go through? Then the representative emailed back and indicated that the only rate she can find is actually $3 higher than the Ramada.com rate. I was appalled and went ahead and cancelled the Ramada reservation and booked otherwise.
