We moved to Vegas, and we went on Vacation to Disneyland 3 times.
The problem is we did everything over the course of 3 days in DLR. I don't consider 3 days a vacation really, thats more like a short trip. Not that I'm saying Disneyland is bad, intact i Love it, there is so much todo in such a small area.
Now we live in California and we only go there for a few hours now every couple of weeks.
I must say, having been on vacation from out of state, and lived near these areas I can tell you for sure that if you want a Vacation, and I mean you want a real vacation than I have to saw WDW is the place to go. There downtown Disney is much larger with more activities, and there is more to explore in WDW parks. Its not all about the attractions. They have such large expansive spaces that makes in your environments feel more immersive, this really shows in all there parks over there theming is top notch.
When your in WDW you don't feel like your in the middle of a city. You take the Monorail in and you feel as if you traveled to a new world "hence the name" the monorail in WDW is actually allot nicer too, its A/C, has standing room and is necessary to to the parks operations to get guests in and out quickly.
I think everyone is forgetting that WALTs intentions was to live in WDW when magic kingdom was being constructed. He was heavily involved in the planning of this park, but unfortunatly passed before it opened.
