It's funny--when I moved to LA in 2007 I heard this on the train, and on the monorail ("Here in Walt Disney's original Magic Kingdom...") and (given I was originally a WDW child) it struck me as petty and smacking of jealousy. But as my time in California grew longer, and I began to appreciate the uniqueness of DL more and more, it no longer bothered me. In fact, I kind of like thinking of DL as "Walt's original magic kingdom" and the original Florida park as "the Magic Kingdom built by Roy to honor Walt"). Neither is superior, they're just different. But they're both magic kingdoms in their own ways...
