I do have to disagree with your comments about California oceanside amusement parks. During the 20's, 30's, and 40's beach parks flourished up and down the California coast from San Francisco to San Diego. They were immensely popular. In their era, these parks had as much impact upon California culture as Disneyland has on present day culture.
As I've stated before, they existed, yes. But the claim that they had "as much impact upon California culture as Disneyland has on present day culture" is simply not true. Most people can name but a handful of these parks, and the ones that existed looked virtually nothing like Paradise Pier portrays them. For example, a key feature of these parks was the bath house, which is not represented in any way, shape or form in Paradise Pier. Granted, it would probably be pretty silly to put a bath house in a Disney park, but excluding one negates any claim that Paradise Pier "represents California's beach culture". They were as prominent a feature as the roller coaster, if not more so. The Sun Wheel is also an inaccurate representation of California oceanside amusement parks. This style of ride existed (and still does today) at Coney Island in New York. This ride is far more representative of Coney Island than it is of anything that ever existed in California.
Disneyland, by contrast, has existed in the public consciousness for over 50 years. It's insane to suggest that the mostly forgotten oceanside amusement parks have had anywhere near the impact on our culture that Disneyland has.
All that aside, let's assume for the sake of argument that these parks had left as indelible mark on our culture as DCA would want us to believe (and as you've claimed). Considering the fact that Disneyland (and all the other Disney parks...including DCA) owe their existence largely to Walt's disdain for these types of parks, isn't is somewhat disrespectful of Walt's memory, and the Disney name, to celebrate this type of park? DCA would have us believe that these parks were such a big part of California culture, that they just couldn't ignore them and omit them from the park. In my opinion, that's just ridiculous and insulting to the public's intelligence. And I think the public has responded and demonstrated our intelligence by generally not patronizing this sad excuse for a theme park.
