Upon our return from Walt Disney World in Florida to California, we decided to undertake a very special challenge: to go from Magic Kingdom in Walt Disney World, Florida to Disneyland, California in one day! 
This took some prep and planning, but it's a Disney Bucket List item that anyone can do.  All you really need is a direct flight from Orlando to LAX and Disneyland late hours (by "late" we mean not closing at 8pm).
We started our day at opening (8am) at Magic Kingdom:

| The Park Plaque in Magic Kingdom | 
We took a photo in front of Cinderella's Castle in Magic Kingdom.
Minnie Mouse is giving me a boost in the photo below:

| That crane is STILL there | 
And on our way out at about 11am, we took a photo in front of the Main Street Station:

We also got "I'm Celebrating" buttons from City Hall in Magic Kingdom.
Then we had to catch our flight to Los Angeles!
We arrived at LAX at about 7:45pm.  We got our luggage, caught the shuttle to the parking lot and headed straight to Disneyland! 
We arrived at about 9:15pm, and we went straight to City Hall for our button and then took our photos:
|  | 
| The Park Plaque in Disneyland | 
|  | 
| Me and my Owl friend in front of Disneyland's Castle | 
|  | 
| Main Street Station in Disneyland | 
We also acquired Fast Passes for Space Mountain in both Magic Kingdom and Disneyland.  In addition to our buttons, those are our souvenirs of a wonderful adventure!
