If traveling via the Hartsfield-Jackson airport without a rental car, the MARTA train system connects directly into the domestic terminal. One-way tickets are only a few dollars, and you can take this both ways between the airport and hotel on the Red Line. This station is 10-15 minutes from the Hilton hotel. This is a much more cost-effective option than taking an Uber from the airport, and you can travel with any luggage.
