Why do you need a trip planner if you know the routes you want to take?
that question is sort of like, since I know start and finish points, why use a trip planner. :s
I use my planner by inserting start and end, then insert waypoints for many reasons. one if the planner doesn't hit a place I want to see, such as Wall Drugs (that is sarcasm) and then enough points along the way to show me mileage and I can spot what is around the distance I want to travel each day. more some days, less for others depending on sightseeing, etc. also which bypass to take at some cities.
and if the route shows roads/areas/cities/etc. I want to avoid,I poke in a waypoint at a different location to force the trip planner to alter it's course.
to blindly follow what a GPS tells you is foolish. once when I had a long stretch down I-85 my gps had me exiting I-85 and going for 20 miles, then taking a left back to I-85. never did understand why that happened.
also traffic patterns change, such as the exit to 17 from 15 at Opal, VA, where in fact they had a sign saying to "not follow GPS directions".
