I believe Expedia's cancellation polciy is friendlier than the Hotwire and Priceline ones (see bottom of post). I think I have a good understanding of the quality-of-hotel per dollar vs. ease of cancellation for hotwire/priceline, traditional web travel agents (Expedia, Travelocity, etc.) and direct purchases from hotels/airlines. I'm going to mull this over a bit. I'm having fun with this game, thanks for all your help! Kevin Expedia's Vacation Package Cancellation Policy: "Different cancellation and change rules apply to each vacation package. Factors include whether a flight was purchased (and, if so, which flight); how many days prior to the departure you are attempting to make the change or cancellation; and which hotel, rental car, and/or attractions were included. Most vacation packages cannot be cancelled but can be changed for a $50 change fee, plus all additional supplier fees and penalties. If your vacation package includes a flight, keep in mind that most economy/coach class flights have an airline-imposed penalty fee of $150 or more per passenger for changes and cancellations, plus any applicable increase in the fare. Tickets are nonrefundable, but can be applied (for a limited time) toward future travel with a vacation package, less any applicable penalties."
