Let me start out with this: I love the new DCA all the way. The Imagineers, Disney execs, construction workers, and so on did a great job and did everything in their power to fix it. But in the end- when I think about- I start to miss the old DCA.
I was at DCA the first month it was open. I was only a mere 5 years old and still in kindergarten, but I can still somehow remember everything so vividly. I practically GREW UP with this park. Disneyland was already a great part of my life, but DCA was something that I could enjoy from the moment it was brand new.
I remember the disappointment of being turned away from California Screamin' because of my height, but the excitement of being able to ride Mulholland Madness. I remember the awesomeness of my first experience on Soarin' and getting soaked on Grizzly and running through the Redwood Creek. I also remember going into Muppet Vision and doing it again and again. I only went into Superstar Limo once, and the best part was just seeing my face on a "billboard" (though my parents had the look of "What the heck was that?"). I remember watching Mushu interact with a person on stage, while talking about animation. As time moved on, I grew up with Flik's Fun Fair, Playhouse Disney (before it got destroyed by the Disney Channel we know today), Aladdin, began to get on Screamin' and Maliboomer, and Tower of Terror had the spot of my new favorite ride at the time. Everything was just a marvel to me in the "other Disneyland park". I became an official Disneyland fanboy around the 50th anniversary celebration, but then my eyes of the actual Disney geek world opened around the time the DCA overhaul was officially announced. I then realized that DCA would never be the same as I once knew it.
Maybe there's just some sort of nostalgic charm to it that people like me grew up with that can never be replaced. That's something that the old DCA manages to share with Disneyland, in my opinion. I made this video below last year when the new DCA reopened, and it just sums up everything perfectly.
