The magic of Disney is that it is so steeped in symbolism and fantasy that it evokes different emotions and memories for everyone that walks through the gates. We all experience similar feelings on some level but on other levels one persons connection to Disney can't be explained to anyone else.
Disney has done such a fantastic job at creating an alternate reality instead of a theme park. When you go to Knotts, Six Flags, or any other amusement/theme park you are still grounded in the here and now. Their rides and shows just act as a distraction. At
Disneyland there is no here and now. There is no California, there is not United States, there is no Earth... there is just Disney. There is only all the magic that is disney. Characters come to life and become people (mice, dogs, ducks and otherwise). Worlds are created by brilliantly crafted environments where you can really feel like a Princess, Jedi, or Pirate. Rides send you to another place and time. All in all the unrealistic washes away and anything becomes possible.
Although everyone had their favorite ride on our trip both my wife and I agreed that the very best parts of the trip were not on rides at all but in those moments where our kids eyes were lit with astonishment and the magic was so strong you could almost reach out and grab it - shows like Fantasmic, and Aladdin, and watching the parade. Eating a character meals... etc. That was what DL is all about to me.
Thats the magic of disneyland... thats what the love for it is... pure unadulterated innocence. As so many others have noted, only at Disneyland is a parent and a child on the same level, can they share the same experience, and see a world through the eyes of one another.
*There's my sentimental moment.... Now to hijack - I've never been to WDW but from so many others I know who have I get the impression that DL does a much better job providing an intimate and magical world seperate from reality, where WDW is more notable for "bigger and better" scale entertainment, and the magic is a little lacking. Is this true? If so, I personally would take DL any day of the week!*
