Reaching the Conference venue
CHES 2019 will be held at the Sheraton Atlanta Hotel, 165 Courtland Street NE, Atlanta, Georgia, USA. To reach the Sheraton Atlanta from the Atlanta airport, take any northbound MARTA train to the Peachtree Center station (all trains departing from the airport head north, i.e., the MARTA only departs from the airport in the northern direction). After exiting the train at the Peachtree Center MARTA station, follow the signs pointing to John Portman Blvd. After walking through the fare gate, follow the signs again to Peachtree Street East.
At the street level turn left on Peachtree and walk to the first intersection (look for the Hard Rock Café) and turn left on Andrew Young International Blvd. The entrance to the Sheraton Atlanta Hotel is two blocks down at the intersection with Courtland Steet.
