1. BGE - because of theming, rides, food, and everything else.
2. I'm staying away from this question.
3. Yes!
4. Sunday
5. Never used it so I can't answer. But I know they reserve row 2 on Apollos and Alpengeist for this service.
Unless you really want to do all that driving to BGE, you might just want to substitute it with Kennywood. Its about 5 hours from Cincinnati and then the next day a 5 hour drive to KD from Kennywood.
BGE is a park that you must go to if you can, but from your plans may be too much.
I almost got in one, I was in study hall sitting in my desk chair when this wannabe gangster tried to knock me onto the floor. I caight myself and stood up to do something back when he ran to the teacher for protection. He never came near me again.
Your right, Richmond to Cincinnati is 8 hours but that is with only a 5 minute stop for gas. Add Richmond to Williamsburg which is about an hour or so, it would be about 9 hours.
Keep in my mind when I did that drive to Cincinnati I left Richmond at 2 am so I didn't hit any traffic.
