This is clearly biased as Easties will prefer WDW as Westies prefer DLR.
I care not for the extravegant this and that, which ultimately have nothing to do with Disney. Disneyland was the first park, and currently holds the title of most visited Amusement Park in the world. Disneyland retains the Disney feel, without the commercialism that runs rampant throughout WDW (how many resorts do you guys have?)
Well, I guess I am guilty of bias as well (100% Californian)...
It is indeed like comparing Apples to Oranges: they are two very different resorts and offer two very different trips. If you want a more on-the-move-constantly to get everything fit into a week, go to WDW. If you want a nice weekend, go to Disneyland.
Am I still showing bias? I think so!
