We went the last two Saturdays to Six Flags Gurnee, IL. Although we live only a few minutes away, we haven't gone more than half a dozen times in the previous fifteen years. But this year, we decided to get season passes and use the park as training for walking around WDW.
So we went the last two Saturdays, and I have to say that versus last August, there is evidence that they're trying to be better than just a teen hangout/thrill park. The aforementioned Wiggles area for little kids, for instance. And they're slowly rolling out decent landscaping (although most of it looks burned out and half-dead right now).
Even with good landscaping and a more family-friendly atmosphere (if they ever really achieve that - the place is 90% teenagers, both customers and employees), they'll never be able to hold a candle to Disney because they have no sense of style.
We rode a dozen rides on Saturday, and by the last one, we were bored out of our minds. They have spinning rides and they have coasters, and not much else for adults. By the umpteenth of either, they all start seeming exactly the same. Partly that's due to the lack of variety, and partly it's because the theming is simplistic at best. There's just nothing to distinguish one ride from another, really.
I will give the Superman and Batman coasters a pass, though. Although Superman has minimal theming, riding a coaster in a lying-on-your-stomach position is novel enough to carry the ride for a while. Batman has slightly more than the bare level of theming, plus the track is decent.
But the rest are just a blur of sameness, for the most part.
And don't even get me started on the fact that not a single cast member smiled at me the whole day - even when I smiled at them and said "please" and "thank you." All I got was grunts in return.
I do hope Six Flags gets it together and transforms all their parks into more family-friendly, clean places. But they'll never be Disney. To do that, you need serious cash, and Six Flags just doesn't have it.
