Why wouldn't you go to Disneyland?!? Unless you are a nutjob Communist, I can't imagine any decent American not wanting to go to Disneyland at least once in their life.
The Disneyland Resort has more rides and attractions in its two parks than all four WDW parks combined. And for the last half decade the Disneyland Resort has had more daily major entertainment (parades, water shows, fireworks) than the four WDW parks combined. When the new DAK water show opens this month, WDW and Disneyland Resort will be tied for major daily entertainment.
And yet Disneyland Resort pulls all of this off in a footprint slightly smaller than the Epcot park/hotel area, as seen in this satellite image taken of Epcot and Disneyland Resort at the same scale.
The Anaheim Hilton is just out of this photo, at the very bottom of the image. It's a 15 minute walk from the Hilton to Disneyland's front gate, or they have shuttle buses that make the trip in 5 minutes. It might be helpful for you to play around on Google Earth, finding the Anaheim Hilton and then seeing how close both parks are.
Here's a view from a top floor room at the Hilton, looking due north towards DCA and Disneyland.
That's the backside of Cars Land in the middle, the Tower of Terror on the right, and Space Mountain and the Matterhorn further beyond. (Disneyland fans can also spot the Hyperion Theatre, Carthay Circle tower, and Big Thunder Mountain in that photo) The squat office towers beyond the parks are downtown Anaheim a few miles north, and those are the Brea foothills 10 miles north, followed by the San Gabriel Mountains about 50 miles north.
This view may change by 2017, as the construction in the foreground is the expansion of the Anaheim Convention Center that will block some of this view.
