Hi Goofyswife,
Let's see, on the way down we drove straight thru. We left Thursday night at about 10 pm and arrived at AKL at 5:00 pm on Friday. There was really NO traffic at night. We took 75 straight down. Make sure you do the West bound bypass around Atlanta and also the by-pass around Macon (much quicker). If you do drive at night my only caution is the big trucks in the mountains. Stay out of their way!!! On the drive home, it took much longer. We left AKL at 8:30 a.m. and made it to Corbin KY by 9:30 pm. LOTS of traffic going home. We left Corbin (Southern end of KY) at 6:30 am and made it home within 7 hours. Traffic Sunday wasn't too bad. We left at night thinking the kids would sleep thru and my 3 yr old did. My 8 yr old couldn't sleep very well. I would probably leave early morning again and stay the night somewhere though. Both kids were SO good I just couldn't even beleive it!!!! We do have a TV in the van which was just a godsend too! There really is any bad constrution delays. We were delayed on the way home in GA near Tifton for about an hour and a 1/2 for no apparent reason. Just TONS of traffic. Hope this helped.
