I went for the first time this past summer. Went to Atlanta Skydiving Center in Cedartown. When my group first arrived we thought the operation was disorganized and while we were waiting we heard that most of the instructors live on site and they had obviously had a party the night before (a few 30 pack boxes of beer in the fire pit outside). Once it was our turn they were great and we clearly saw that they knew what they were doing.

I would suggest tandem for the first time, you dont even notice anyone is strapped to you until the chute opens and he/she does all the work to get you to a smooth landing. While we were there I watched a guy go AFF for the first time after having already done several tandems and his landing was rough and resulted in a broken finger.
