I was only at Cedar Point once, last month. We bought the $65 fast lane passes. I agree with pretty much everything gaycoasterguy said about Great America vs. Cedar Point. CP's Max Air is clearly better than SFGAm's Revolution. Wicked Twister is about the same as Vertical Velocity, but a little better because WT twists at both ends. Also, the line for WT moves much faster than V2 for some reason, even though there wasn't a Fast Lane at WT. CP's Millenium Force has a steeper and longer first big drop than SFGAm's Raging Bull, and in my opinion the view of the lake on Millenium Force is better than the view of the tunnel of Raging Bull, but that might be just because I'm so used to Raging Bull. I rode Gatekeeper twice, the second time we were stuck on it for about 15 minutes, Gatekeeper and Top Thrill Dragster have to be shut down when there are high winds to to its proximity to the lake, something SFGAm regulars don't necessarily think about. We asked for a partial refund for the fast lane passes because Gatekeeper and Top Thrill Dragster were down for so long, and they refunded us $15 per pass ($50 is the cost of a fast lane pass that doesn't include Gatekeeper or Top Thrill Dragster), so that was fair.
Other than X-flight, the only thing SFGAm does better than CP is the sports bar. SFGAm's sports bar has Bulls/Blackhawks/Cubs/White Sox/Brewers/Bears/Packers jerseys and decals. Cedar Point's sports bar has those generic sports decorations and wallpaper that looks like it belongs in a child's bedroom.
SFGAm in my opinion is not worth going to unless you have a season pass or you use a bring a friend for free or $10 or maybe $15 coupon. It is not worth buying any food items at SFGAm unless you have the season dining pass. SFGAm foodservice operations are so slow you can probably go outside the park to a local restaurant and back and it would still be quicker than waiting in SFGAm food lines. It will also be better quality and cheaper, and you will get more exercise. SFGAm is absolutely a season pass holder park, which reminds me: Don't expect short lines for Coasters After Dark this Friday simply because it's for season pass holders only. Pretty much anyone who goes there is a season pass holder.
