It allows you to plan a trip to see different sites and print out a list of all the things you’ve planned so you can actually do them when you get there. They integrate the use of Yahoo Maps and you can also see other people’s trips to get some ideas. It looks like a handy tool to use next time you’re planning a trip.
Update: I found another site which is similar in nature called We just got back. The tag line is travel advice you can trust from families who have been there.
