The Walt Disney World monorail system--a 14.7 mile highway in the sky--has carried more than a billion passengers since 1971.
On select days, WDW resort guests are allowed to enter a theme park one hour before the general public. It's known as the "Extra Magic Hour."
Certain attractions keep shorter hours than the Magic Kingdom itself; for example: The Hall of Presidents and The Tomorrowland Transit Authority. To make sure you catch all your favorites, check a times guide when you enter the park.
