How is the parking around the Atlanta Centennial Olympic Park? Is it really bad there?

Yes! Sorry to tell you that. But, the parking is really bad all throughout Downtown, Atlanta. Centennial Park is really close to the CNN Center, World of Coca-Cola, and Georgia Aquarium (to name a few). So, this area is always hectic. If you're lucky, you might be able to find street parker and just pay the meter. But, most likely, you might have to park in a lot or nearby garage. Parking is usually somewhere around 5 to 10 bucks. Good luck! ;)
