This is just my two cents.
Would you drive eight hours to Six Flags Over Georgia to be horribly disappointed? I don't think you would want to. On this past Sunday, I went. Rain policy is that all rides close if there is heavy rain, lightning, or high winds. It was very, very lightly sprinkling out. Not one coaster or flat ride was open and they closed the whole park at noon, with no warning at all and no refund. We tried to get our refund, but we were escorted out of the park by the security and treated extremely rudely by numerous employees.
Take my advice.
It's not worth it...
