Trip Planning Software - Not Sure About MS Street & Trips

I use the KOA trip planner for basic routing, then plug destination into the navigator and go. Too much effort to try to analyze everything IMO. This way you have basic idea of route, can look at unexpected roadside attractions and not have to worry about anything you also know approximate time and distance involved and cross check with the navigator. traffic delays will pop up no matter where you plan. Nashville is terrible as is cinncinnati and and everything in between.
