We live in the NW suburbs of Atlanta and have done the drive to HH many, many times.
I-16 from Macon to Savannah
is pretty desolate. It's about a 150-mile stretch.
We usually try to time the drive to be able to stop in Macon to get something to eat; or maybe I should say we stop to eat in Macon no matter what time it is because it has the best options!

(Exit #169 of I-75 has several places right near the exit.) Other than that, there are only two decent exits: Dublin (which is about 50 miles outside Macon) and Metter (which is about 50 miles from I-95). Both of those exits have a few chain fast-food places close to the Interstate.
I often make the drive solo and tend to plan my stops for the Interstate rest areas, since they're normally kept pretty clean and also have security. On the way from Atlanta to HH, there are rest areas in Macon (just before the I-75/I-475 split), Dublin, and the SC Welcome Center. On the way back to Atlanta, there you have the Georgia Welcome Center and Dublin. (The one in Macon is along I-475 for northbound travelers, so you miss it.)
It's really an easy drive. There is rarely much traffic on I-16. I like to download an audio book for the trip so I don't have to play around with finding radio stations. Usually by the time the drive is over, the book is pretty much done as well!
