I have used all the major sites (expedia, travelocity, orbitz, hotels.com, bookit) for both business and personal travel and the only one I ever had trouble with was hotels.com. They couldn't find the hotel reservation for one of my employees and of course the hotel was booked as were all hotels nearby. It caused a big headache for the employee. Then when I contacted them and forwarded the email confirmation that I had received from them, they still couldn't find the reservation. It really amazed me. Plus they weren't helpful or sympathetic or anything. But with that said, a perfectly reputable company can make a mistake. Good luck with booking the room. I am sure everything will work out great. Just call to confirm a couple days before you leave to make sure they have the reservation.
