After reading so much about DCA on here, the first time I went there was July of this year.
Even after all the stuff I have read, I still went in with an open mind. "It can't be THAT bad..." So I went and experienced it.
And I liked it.
Sure, it has many glaring flaws, which I'm not going to repeat here, like theming, lack of attractions, etc, but there are a lot of cool things about it. It is fun. And I had a good time. Screamin' is my favorite Disney coaster in the US. Monsters Inc is ADORABLE, though doesn't fit the California theme at all, and some areas of theming, especially, the GRR/Redwood Creek area, are absolutely gorgeous. Do I think the billion dollars will help? Of course. Will the retheming make it a more "Disney" experience? I sure hope so. But, there are good points to DCA, and I am glad I got to experience the park in it current form, just to realize that everyone can form their own opinions. It's not a stellar park, but it's a great diversion, especially when Disneyland is way too crowded.
So, if you haven't been, and only read about it. Don't knock it till you've tried it. It's not so bad.
