first, i have to add as a disclaimer--we are huge disney fans and have been numerous times, but i have to disagree with the six flags thing. my dh and i took our ds13 and his friend day before yesterday and found it to be not that bad. we used the valet parking ($25) which had us literally at the front gate, and paid $26.42 for each ticket online using a discount code. there were so few people there the entire day, we were actually shocked! the kids walked right on almost all the coasters, even goliath, and the most they had to wait was about 20 minutes. we stayed from park opening to 6:30 and they got in 25 coaster rides

!
we didn't see the roving gangs of thugs that we expected and while the park employees are teens for the most part, we didn't find any rude or obnoxious. we even had quite a few who were very helpful with directions and pretty much everyone smiled and said have a great day. i will be the first to say it's not disney, and i don't think it is fair to compare the 2, but we didn't have any problems letting the kids run ahead to get to rides and we met up with them at the ride exits... i'm disabled and can't walk fast. they had their cell phones so we could get them/or viceversa and they said that they didn't have any problems with thugs or bullies.
and as for the distance from augusta, we live in loganville, ga which is about an hour from augusta, and it only took us an hour to and from the park, using I20 if that helps judge travel time.
again, it is NOT disney and i think it is probably geared for teens who can ride roller coasters since that is pretty much all that is there. also it is EXTREMELY hilly and if you have any walking issues, be prepared for that. one more thing about the reports of it being super-ghetto like, we struck up conversations with a lot of parents who come and bring books and sit in the nice shaded areas while their kids do their thing for the day (and they were just nice, normal looking suburban moms and dads not drug lords or pimps)!
