gtrot was listed as a social travel site that makes trip planning easier!
“Gtrot is similar in some ways to Gogobot, but it is different enough that you should check it out as well. It also uses your social network to help you plan your trip. The website suggests the best things where you’re going based on your likes, friends check-ins, and events happening during your trip.
Something else that Gtrot will do is to discover any deals in the places you’re going for the time you’ll be there. For example, if there’s a Groupon for a restaurant that your friends like, Gtrot will let you know it’s available and that you might want to check it out.”
