Disneyland's Tom Sawyer's Island
Tom Sawyer's Island is one of the only parts of the park that was designed by Walt Disney himself which has changed very little over the years.

Ok, so the address for Disneyland Guest Relations is 1313 Harbor Boulevard, Anaheim, CA. When Disneyland was built there was nobody else on Harbor Blvd. So how did we get to the 1313 bit?

Simple. The thriteenth letter of the alphabet is "M"... So 1313 is "MM".

-The murals in the Bibbidi Bobbidi Boutique in Cinderella's Castle @ WDW are set up to look like the Castle Garden that her and Prince Charming danced in during the ballroom scene.

-The clock in the entrace area by the cashwrap is perpetually set to "12". This is so that the clock will never chime "after midnight" and return all the princesses to their "normal state"--thus perminently preserving the magic.

-Imagineering confim that there will *not* be a hidden mickey in the boutique. It's said that the logic behind this is that each hairstyle offered contains a "hidden mickey", so when you go and get your hair done, you're wearing the hidden mickey.

Small end to Main St USA
I suppose everyone knows that the end of Main Street nearest the Hub is both narrower and lower than the City Hall end? The difference is only a matter of inches but it adds to the illusion that the street is much longer than it really is. It is a visual effect that uses your expectation of perspective.
