14 was my first year. I was there from Saturday to Saturday. I was camped out on the main line and flew there also. Like
@ChickenBalls stated, the best time to get some flying in with the least amount of wait time is Saturday through Tuesday. Also, if you are like me you enjoy flying around dusk and things settle down quite a bit on the main line the last hour or so before sunset. After dark I would head down to the 3D line and watch the craziness set in! If you are planning on getting good sleep while you are there, it will only happen after you are flat wore out from trying to take everything in. My daughter went with me and she was already trying to plan the trip for 2015 before we left! I am hoping to make it, but she graduates on the Friday at the end of Nall, so I am not sure I will be there this year
If I can sneak down, a 14 hour drive for me also, I will go and just enjoy everything that is there for a few days and then head back home. IT IS WORTH IT!!!
