To me, disneyland is like the place I (as a local) love to go and show off to my out of town friends and family. "Oh! Hey! You're coming for a visit from NorCal/Mexico/Colorado/NY? Well, we are going to Disneyland and I'm going to show you how awesome it is!" I then put on a pair of mickey ears and my goofy Disneyland Tourist Smile and have a great time hanging out and showing off what is in my backyard!
From people I have met from other places tho, it is DisneyWorld that is the mecca to all childhood family theme-park vacations. A complete weeklong vacation. A Disneyland is the drop by 'oh I just happen to be in the LA/OC area might as well stop by for a day" place.
