Sites such as Kayak.com dive right in, navigating sea, sky, and lodging travel choices. Plus, it offers free apps for your iPhone, Android or BlackBerry.
Check Yapta.com to track fares and hotels. If a price drops significantly, Yapta will e-mail or Tweet at you so you know to request a refund or credit. And Priceline.com is still a favorite for hotel discounts and car rental deals.
