Flying in
Fly into ATL, Hartsfield-Jackson. It is Delta's main hub, with nonstops from most US cities.
You do not need a rental car to reach the city. MARTA's Airport station sits at the west end of the Domestic Terminal, by baggage claim. The Red and Gold lines run north through Five Points downtown and on to Midtown.
Locals split the metro at the Perimeter, the I-285 loop around the city. ITP is inside it, OTP is outside, with Alpharetta and Roswell OTP to the north. Book your room after the venue is settled. ITP and OTP are different commutes.
Come in Thursday if you can. The BeltLine's Eastside Trail runs from the corner of Piedmont Park past Ponce City Market into Old Fourth Ward and Inman Park. Walk it the evening before day one.
March weather
Highs in the mid 60s, nights in the mid 40s, and March is one of Atlanta's wetter months. Pack layers and a rain shell.
Tree pollen peaks in late March. The yellow dust on every car is pine, but oak and birch cause most of the sneezing. If tree pollen gets you, bring your allergy medicine. Three days of deep breathing through a stuffed nose is no fun.
