We are in Greenville now and planning a visite to Atlanta in weekend. I have went through all the information in TRIPADVISOR. We want to visit Martin Luther King Jr. National Historic Site、World of Coca-Cola、Margaret Mitchell House and Museum、CNN Center、Centennial Olympic Park、UNDERGROUND ATLANTA. Due to the crowded traffic mentioned in this website, we'd like to park our car somewhere and go to those attractive spot via MARTA. so what's your advise for parking and route connecting above stops. can the subway/railway take us all those spot? Need your suggestions. We really appreciate it very much.
