Although the U.S. Census lists the population of Lake Buena Vista City at less than 25, this bustling area forms the very heart of the Orlando amusement mecca. Surrounded by residential neighborhoods, Lake Buena Vista hosts millions of annual visitors in scores of hotels, villas, and resorts. Walt Disney World is synonymous with Lake Buena Vista, covering 47 square miles with internationally famous theme parks, creative water parks, the nightspots of Pleasure Island, the restaurants along Disney’s BoardWalk, and the Factory Stores at Lake Buena Vista. More than 2,500 acres of the property are occupied by hotels and villa complexes, each with its own theme and recreational facilities. Epcot is the second largest theme park after Disney’s Magic Kingdom, blending a science exploratorium with a world's fair. Disney-MGM Studios is devoted to the film business, while Animal Kingdom focuses on creatures. Universal has reinvented itself as a premier destination through a $3 billion addition of new resorts and parks.
