I've never understood priceline so I stick with hotels.ca (the place with the stupid Captian Obvious commercials). The price is usually competitive but we try to double check with other sites and direct to ensure that we are paying a fair price. They have a rewards program that gives us free nights after ten nights of hotel stays. They may not be the cheapest but they have never screwed up a single booking in over a decade of online bookings. I always make bookings that can be cancelled for free because travel plans can change.
Is hotwire cheaper than hotels.ca, bookings.com, expedia etc?
