We will be making our third trip to WDW this July. I typically prefer the interstates and as such I have always taken I-20 east to Shreveport then I-49 down to I-10 and across to I-75. Street Atlas likes to route you along I-20to Jackson then down US49 to US98 to Mobile. Has anyone driven this route? It is about 50 miles shorter than the all interstate route. I'm guessing that it is pretty much a wash on elapsed time since I assume the speed limits are lower and there are probably more stops because of all the towns along the way.
