Disneyland

Disneyland, is a popular American theme park.

Disneyland was mentioned by the Navarinos as their destination. (DW: Delta and the Bannermen)

In the Ninth Doctor adventure novel, Winner Takes All, The Ninth Doctor wasn't too impressed with Disneyland, as told Rose he can take her to a place with real talking mice.

Behind the scenes
During the late 80s (even before the original series was cancelled), early 90s (before the tv movie was made) when the Walt Disney Company (the people who own Disneyland) were on a buying frenzy and bought things like the American Broadcasting Company, ESPN, and others. Disney attempted to buy the rights to Doctor Who and its video library. Had Disney been sold the rights they would have set up a walk-through exhibition of what it's like inside a TARDIS at Tomorrowland. They even planned on whether the need comes, they would announce who the next Doctor would be at Disneyland during a press conferance at Tommorowland (rather then at the BBC news studios like the BBC did)

During the 70s, Doctor Who attempted to have a serial filmed on location at Disneyland involving The Third Doctor and then The Fourth Doctor tracking down an alien at the place. However budget restraints forbid it.

Many fans speculated that if Disney bought the rights to the franchise, Tom Baker (the most recognisable man to play The Doctor) would have been named a Disney Legend (what Disney calls their Hall of Fame) an award given to those who have made an outstanding contribution to The Walt Disney Company.
