During the week is always less crowded. But the nights at light are terrific. How about arrive just after a late lunch and stay a few hours after dark? Check the calendar for timing of events in the evening. Should be fun! Food is expensive, just FYI.
Go to the website. They have a calendar that will show you the dates .
After 6 pm through the week. Less people
Look online at the Atl Botanical Gardens calendar. You'll see dates during the week where tickets are less expensive than on the weekends. Parking at the entrance was $5 when I went at 5:30pm. The earlier you go the better. Parking fee increased to $10 when I left.
