I'm about to graduate my AAF course at Skydive atlanta. I'm on level 6 and it's been a great time there. The staff is cool and professional. Lots of couches and chairs to sit on while waiting. The instructors actually care about how you are doing and care for your safety.
I would recommend that you either bring something to eat or have money on you to order chinese/pizza while you're there. Since it's only open on the weekends, a lot of loads are filled with tandems, so if you're doing AAF, sometimes you might have to wait a little while before an instructor is able to go with you. But once you hit level 4 you only need 1 instructor so it's pretty good from there.
Lots of friendly people there. can't wait to graduate AAF and get my A license
