I like to check the deals at hotels.com, then go to the hotel's web site to see if they offer a low-price guarantee. I was able to get a significant discount on a hotel in Toronto a few years back by doing this - the Expedia price was a certain amount, and since it was lower there than what the hotel was advertising on their web site, the hotel gave me the Expedia price plus an additional discount. Usually you can get a great deal too through a hotel's site if you have AAA/CAA, or are willing to do a nonrefundable advance purchase at least 21 days out.
