The site uses permission-based Facebook data – including where your friends live, where they went to school, and places they’ve “checked in” – to show friends who live in your destination or have been there before. Users can notify friends about a trip or ask for advice via Facebook within one-click. Responses are automatically pulled back into your trip on Users can add past and upcoming trips and instantly connect with relevant friends. The site alerts members when friends share overlapping trips or travel to their home city. gtrot also searches hundreds of sites like Groupon for the best daily deals available in top destinations to help travelers save money and discover new experiences. The site includes several new features including gtrot Deals. Through recent partnership with Local Offer Network, this feature enables gtrot users, who have shared their upcoming travel plans, to receive curated local deals for the cities they will visit during their trip. Deals are selected from thousands aggregated each day by Local Offer Network's DealWire™ platform. Other features include: - Share travel plans with Facebook friends and Twitter followers - Easily manage itineraries - Get advice from people you trust – your friends - Connect with Facebook friends who live at or are visiting your destination when you are - Get alerts when friends plan a trip to your city - Post photos and reviews of past trips and share them with your Facebook friends “There are several travel sites that offer recommendations, reviews, and travel Q&A,” said Zachary Smith, Co-Founder and CEO. “But we believe the best way to get ready for a trip is just to share your plans with friends. You’ll get the advice you need, without the noise, and find friends to meet up with in your destination. It’s such an easy and rewarding way to travel.” Since launching in beta at Harvard in late 2009, gtrot has attracted nearly 6,000 users and a venture round from Lightbank, the investment fund created by Groupon co-founders Eric Lefkofsky and Brad Keywell. “Online travel planning is still really messy, it’s very difficult to find recommendations tailored to your interests,” said Brittany Laughlin, Co-Founder of gtrot. “Whether you’re visiting a friend in a familiar city or flying halfway around the world, we want to connect you with personalized information and deals that will make your trip awesome.” Related Link: gtrot
