WorldWaypoint is a Google Maps service that allows you to map your favourite locations.
Using WorldWaypoint you can save your favourite locations with a description and a picture of the location. Once you have saved a location on WorldWaypoint you are given a unique URL to your created point that you can then share with family and friends.
Worldwaypoint also includes a trip planning application. After you have created a number of waypoints to your favourite destinations you can plan a trip that takes in your saved locations. Just specify a start date and end date for your trip and add the destinations you wish to visit.
When you have competed your itinerary you can print out a PDF file of your planned trip.
