What's unique about Gogobot (free) is that it gives you suggestions on where to go and what to see based on what type of traveler you are. Looking for something more active? Family-friendly? You'll find it all here. Save the suggestions to an itinerary and pull them up when you're out exploring, or search for new places to visit based on what's nearby. You can even make collaborative trip plans, looping in family and friends to add to group itineraries.
