For one, to James, who has sentimental value to California Adventure? And if they do, there have been so many changed to the Pier and the rest of the park already, so i dont get where that plays a part in California Adventure.
You would have a decent case with that if someone was saying turn Main Street into a toon town area, but not the ever changing Pier.
To the original poster, i think thats a very cool idea. What i think, to add on to that, is that it should be a Vintage toon town. Have a toon town version from when Disney started. With silly symphonies, and the fun wheel, being representing of the Disneyland past, i think that it would fit in perfectly.
I also agree with the pier thing, but i do enjoy the boardwalk. The games are even the games of Boardwalk, not pier. Its interesting.
