would be known as "Walt Disney World", in his brother's honor. In his own words: "Everyone has heard of Ford cars. But have they all heard of Henry Ford, who started it all? Walt Disney World is in memory of the man who started it all, so people will know his name as long as Walt Disney World is here." After the dedication, Roy Disney asked Walt's widow, Lillian, what she thought of Walt Disney World. According to biographer Bob Thomas, she responded, "I think Walt would have approved." Roy Disney died at age 78 on December 20, 1971, less than three months after the property opened. Admission prices in 1971 were $3.50 for adults, $2.50 for juniors under age 18, and one dollar for children under twelve. 1980s–2020 Much of Walt Disney's plans for his Progress City concept were abandoned after his death and after the company board decided that it did not want to be in the business of running a city. The concept evolved into the resort's second theme park, EPCOT Center, which opened in 1982 (renamed EPCOT in 1996). While still emulating Walt Disney's original idea of showcasing new technology, the park is closer to a world's fair than a "community of tomorrow". One of EPCOT's main attractions is the "World Showcase", which highlights 11 countries across the globe. Some of the urban planning concepts from the original idea of EPCOT would instead be integrated into the community of Celebration, Florida, much later. The resort's third theme park, Disney-MGM Studios (renamed Disney's Hollywood Studios in 2008), opened in 1989 and is inspired by show business. In the early 1990s, the resort was seeking permits for expansion. There was considerable environmentalist push-back, and the resort was convinced to engage in mitigation banking. In an agreement with The Nature Conservancy and the state of Florida, Disney purchased of land, adjacent to the park for the purpose of rehabilitating wetland ecosystems. The Disney Wilderness Preserve was established in April 1993, and the land was subsequently transferred to The Nature Conservancy. The Walt Disney Company provided additional funds for landscape restoration and wildlife monitoring. The resort's fourth theme park, Disney's Animal Kingdom, opened in 1998. In October 2009, Disney World announced a competition to find a town to become twinned with. In December 2009, after Rebecca Warren won the competition with a poem, they announced the resort will be twinned
