The Aquarium is open! Go visit the largest aquarium in the Western hemisphere. They are currently working on an expansion to the aquarium set to be completed by Fall 2020 and it includes a shark exhibit. You must buy your tickets online. Tickets are $32.95 for all ages (2 and under are free). Masks are required for everyone 3 and up. They have also included social distancing measures and have limited occupancy for your safety.
Literally across the grass from the Aquarium is the World of Coke. Come taste the different Coke flavors of the world and discover your new favorite flavor. You can also learn about the history of the company and peek into the secret vault. Adults are $17 and children are $13. Military members can get in for free with ID.
So...I've actually never been here but chick-fil-a runs it so you know it's good. This museum includes over 50 interactive exhibits and includes a 45-yard football field. Tickets are about $23 for adults. They do have military and student discounts but you have to buy those tickets at the box office.
The themes in the garden change every season. They do have a few sights that stay all year round like the goddess by the waterfall. Normally during December, the Christmas lights will be up and you will be able to walk through a lit-up garden show in sync with different musical tracks at night. Also, the gardens are right next to Piedmont Park so you could enjoy a stroll around the park before or after your garden visit.
