This is something I'm actually surprised to have not found in this day and age. I'm looking for an online mapping service that allows me to put in a start point and multiple destinations. Then it re-orders the sequence of destinations so that I travel the fastest/shortest possible route. Four(ish) years ago, MapsOnUs had this function when it was part of Switchboard.com, but it does no longer offers (it was called "Plan Best Tour"). None of the other major online map players offers this. Is there any smaller site that does this? Or maybe a Google Maps mash-up? Thanks.
