For last minute trips, there's always Site59.com. Also, try the airline sites themselves, as they often have flight/hotel packages (pulling from the same consolidator inventory as the Orbitz/Expedia/Travelocity/Site59 package pull from & you can sometimes get bonus miles for booking through them). Lastly, for a Disney vacation, check out places like AAA travel agencies - they're free for you to use if you're a member & you can get competitive prices from them too (and still get your hotel/air miles).
