A Map on Roadtrippers - Maps built for travelers.
So far been using roadtrippers.com to plan the road trip. Tried other apps but i like the way this one really integrates with the map. Not sure how it will do mobile. On PC i can put as many stops in as I like. There are categories like entertainment or nature. So I look at the route, mouse over the little green arrows and find things that might be of interest to me. Or I can choose a place and find hotels near that location with pictures and reviews. ALSO (not done yet) shows how long a drive between places and the cost of gas. So we can all pitch in before the road trip. ALSO ;) you can move and add things in the list, change the order. I sure hope this works on my phone cause planned the trip off of it so far. I havent figured out how to save it yet though.
