- Disney's MGM Studios was a big Film Studio before turning into a theme park
A studio did exist in this location before the park opened, but it did not produce films related to any of the attractions in the theme park.Why it has survived so long: For one thing, most people cannot tell you the difference between Disneyland and Disney World. Since Disneyland is on the outskirts of Los Angeles, people assume Disney's Hollywood Studios is somehow involved with the real, functioning studio. Obviously, when they find out it's a theme park in Orlando many people abandon that thought, while others seriously think that Casablanca and the Wizard of Oz were filmed in the Florida swamp.
- The five-legged goat at Disney's Contemporary Resort has a twin in Magic Kingdom
Nope, there is no five-legged goat in "It's a Small World". Why it has survived so long: People love any fun facts that seem like conspiracy theories or some sort of secret hidden from "normal" park-goers. People say this has something to do with the occult- it's really a stretch.
- Cinderella's castle can be taken apart
People think it can be dismantled to avoid potential storms damage, but it cannot. Why it has survived so long: People are willing to believe anything preposterous about Disney these days based on nothing more than how much money the company has. But building a structure that large and that sturdy that can be taken apart on the off chance that a hurricane can destroy it is ridiculous. If a hurricane was strong enough to do that much damage, the rest of the park would be in terrible shape- and no, Disney World is not made up of all collapsable buildings.
* Note: The high-flying gondola ride over Fantasyland was actually removed in case of hurricanes.
