Thinking about going in Aug. I don't like alot of the roller coaster that go upside down. Is there really enough to do for 2 days or can you see everything in one day? I have been a few times before, but looks like there is more to do in the summer. I usually go in the fall. I don't want to waste money on 2 days if I can see everything I want the first day. I know it's only $20 extra for the 2nd day, but with parking added in it can get expensive fast.
