As much fun as planning a trip can be, there's always so much stress and worry when it comes to prices. Am I getting a deal? Will flight prices go down? Should I book last minute? Another reason why I absolutely love technology — enough with the travel booking stress! Farecast and Kayak are great for getting price alerts on flights, but what if you want an alert service that basically acts as your own travel agent, you've got to check out Hotwire's latest feature (it just launched yesterday!) Trip Watcher.

With Trip Watcher you can watch specific travel itineraries and get email alerts about price drops for hotel rooms, car rentals and airfares. Just input dates (can be up to a sixty day range), destination, possible airports and Trip Watcher will compare them with all of their Hotwire itineraries. Once your Trip Watcher page is set up (you can include up to 25 trips), there will be a running history of your requested dates and destinations, plus the prices changes for each!
