I agree- avoid Atlanta during rush hour if possible. Especially if it is raining. We've traveled down many, many times by van. We used to pace ourselves - so far to Paducah, Nashville, Chattanooga, Atlanta, so on. It takes about 16 hours from St. Louis. Sometimes we drive straight through, sometimes we stop either north of Valdosta, or just south. When the kids were smaller, they liked to stop several times south of Atlanta to break the driving time up. I think they were those Magnolia gift shops. A must for us was a television/vcr. You can tell we haven't driven for a few years, since now everyone has a DVD. The drive isn't bad at all. Nice interstates all the way - once you get out of MO. Have fun.
