When we book our trip we always check for the best price by going to bookit.com, expedia.ca, Travelocity.ca, hotwire and westjet.com/vacations.  We have gotten amazing deals from bookit.com. We once booked 5 nights at the Venetian (Which is usually $300 and up per night), airfare, breakfast every morning for $550 each taxes in! It is like the stock market when you see a good deal you have to be ready to book it before the price goes up.
