The Fiesta Atlanta event takes place over Cinco de Mayo weekend in Centennial Olympic Park, which is in walking distance from both the GWCC/Dome station and the Peachtree Center station. If you are coming from the north or south lines, exit at Peachtree Center so you can avoid transfering trains. Likewise, if you are coming from the east or west rail line, get off at the W1 stop.
After getting off the train at the Dome station, follow the signs to the Philips Arena exit out of the station. Go up the escalator and stairs and keep walking straight ahead and you will reach the park.
If you exit at Peachtree Center, take the Harris Street exit out of the station then follow the signs to Peachtree Street West. At street level, you can walk west down Andrew Young International Blvd., Harris Street or Baker Street and end up in the park (see map).
