With Christmas Break fast approaching, and Spring Break travel planning about to get into full swing, The college-exclusive Gtrot is here to coordinate and share your travel plans with friends.  

There’s no signup required, save for connecting your Facebook account, so you can immediately use their online booking interface, powered by the incomparable Kayak, to find the best deals on hotels, flights, and cabs.  Once you book your trip, you can share as much or as little information as you want about your itinerary with your Facebook friends, and even see which met-them-twice Facebook acquaintances will be at your destination at the same time.  Gtrot’s cleverest feature though is the ride matcher, which facilitates cab-sharing with your buddies to and from the airport, or around town.

Obviously, this is the kind of service that is only useful when a lot of your friends are utilizing it, so spread the word!
