Yes, I know several trip planners that let you add in stops along the way to your destination, but you have to set the visit sequence yourself. What I am hoping for is a trip planner that will let you put in a start point, an end point and various points of interest you would like to visit along the way. I would like a program that picks the order in which those intermediate points would be visited.
(I"ve heard the delivery companies have this capability along with chosing a route that maximizes right hand turns to minimize traffic delays).
