South - ATL - Where to leave cars?

I will be staying in ATL for a night on each side of a trip. My husband and I will be driving form different states so we will have two cars. Any recommendations on where to stay and leave the cars for 5 days. I have checked www.park-stay-fly.com & www.parksleepfly.com but they don't discuss the 2 car issue.

Any other suggestions woudl be great.

THANKS!
