I will be traveling from St. Pauls, NC to the Biloxi area in a week or two. I planned to go straight down I-95 to I-10, keeping it simple, staying on big interstate highways ... but it looks like I can save a couple of hours by cutting inland through the Atlanta area. Is it worth it?

Factors: I am completely unfamiliar with the area. I'm in a hurry but more concerned about having an easy drive than setting speed records. Whaddaya say?
