Unfortunately, before the park was completed, Walt Disney died and the task of completing the park was left to his brother, Roy Disney. Roy worked hard to complete the park the way Walt had envisioned it, and five years later, in 1971, Disney World was ready for visitors with its first park, Magic Kingdom. Finishing the park was one of the last things Roy did, just three months after his death. Even after the passing of the Disney brothers, the park continued to expand and is still expanding. In order the major expansions of Disney World are Epcot in 1982, MGM Studios, now known as HollyWood Studios and Typhoon Lagoon, in 1989, Blizzard Beach in 1995, and finally Animal Kingdom in 1998. Many expansions and upgrades have happened and are currently happening all also inside each of these parks. Today the park includes four theme parks, two water parks and twenty-five resorts, all within the 47 miles of land that Walt purchased in the 1960s. Less than 1/3 of the purchased land has been used. The rest of the land that is not used for parks or resorts is intact or used for conservation purposes
