The Hyatt Place Atlanta/Downtown is near two MARTA stations at 330 Peachtree Street NE. Nearby attractions include Hard Rock Cafe’, Peachtree Center mall and offices, Georgia Aquarium, Centennial Olympic Park, World of Coca-Cola and the Imagine It! Children’s Museum. With daily parking at the hotel $22/day, consider taking MARTA from the airport or other destination and walking to the hotel.
The closest MARTA station is the Peachtree Center MARTA station on the red/gold rail line. Follow the signs to the Harris Street exit and then to Peachtree Street West. At street level, turn left along Peachtree Street and walk just over two blocks.
Or, exit at the Civic Center MARTA station, also on the red/gold rail line. Exit the station and head south (toward the skyscrapers) on West Peachtree Street. When you get to the edge of the small park, turn left on Simpson, then left on Peachtree Street. The hotel will be near the corner (see walking map from both stations).
All trains departing the airport stop at both Civic Center and Peachtree Center, so merely get on the first train that arrives. The MegaBus also stops at the Civic Center Station.
