Okay Disney lets get this straight.
The slogan of the Disneyland Resort is The Happiest Place on Earth.
The slogan of the Walt Disney World Resort is The Most Magical Place on Earth.
The slogan of the DisneyParks fiasco is Where dreams come true.
Slap Where dreams come true on all you want as long as it is DisneyParks branded merchandise. Just leave the Disneyland and WDW-specific stuff as it is.
