This is a nice article that sums up the differences in experience at Disneyland in CA, and Walt Disney World in FL.
The size of WDW is, to me, an advantage, as I had stated a while back. There is just this lack of a "buffer" between the unorganized, real world and the theme park at Disneyland. Whereas at WDW, the size allows it to force the guests to emotionally, or psychologically separate themselves, consciously or unconsciously, from that real world. And certainly, WDW is a resort in the truest sense.
