For those not wanting to rent a car, you can take MARTA from the airport to the North Springs station ($2.50 roundtrip per person / 50 minutes). The hotel is roughly 10 minutes from the MARTA station.
The ceremony, reception, Friday night dinner and Canton Street are no more than a 10-15 minute Uber/Lyft ride away.
Also depending on your arrival time into Atlanta we’d be more than happy to make a few airport runs Friday morning.
