You need to do everything you can to avoid Atlanta on Friday between noon to 7 pm. DH is leaving Friday too heading south ... and leaving before noon. I will often try to clear the city on a Friday afternoon to FL (haha, maybe next week so I can have a full Saturday at Disney) where I pick up my DS at 2:30 and we head straight into the beast. Minutes can alter our trip drastically to where I'll pick him up early at 2 to get ahead on a normal Friday.
- Leave as early as possible.
- Don't stop unnecessarily to delay entering and leaving the beast.
- Make sure you have gas before getting in to town in case you are parked on the highway.
- The Eagles Landing express lanes are glorious, I use my Sunpass, I think also NC Pass works.
- IF you choose downtown use the HOV lanes (am guessing you are not alone).
- Downtown likely going to be a cluster, especially with the Football and DragonCon folks arriving.
- IF coming down I-75 I'd likely take 285 West around past the airport and then get on I-75.
- Watch your mobile map apps for any accidents or closures, but otherwise don't get off and try to beat the traffic, it inevitably fails.
You already know what the AL route will cost you ... assuming no issues. You might get lucky with the Atlanta route and there are options so I would likely stick with that leaving as early as you can.
May the force be with you!
