We're flying into Atl from MN Dec 13-16 for a wedding and one thing most really want to do is tour CNN while there. We don't plan to get a car as family will pick us up for wedding events. Is a Marta station (for our trip to/from airport) nearby CNN and also near a hotel nearby someone could recommend? Should we stay real close to CNN or is there a more interesting option, say midtown, near the Marta to get to CNN easily on Friday morning and the airport on Sunday? Most family is thinking they'd like to stay within walking distance to CNN and Marta.
