There is no more successful theme park resort than Walt Disney World. Covering over  27,258 acres (nearly 50 sq. miles!), the Walt Disney World Resort houses 27 themed resort hotels, 9 non-Disney operated hotels, four theme parks, two water parks, multiple golf courses, a campground, entertainment venues, a full shopping center, and millions of magical memories.

Some Interesting History:

As businesses sprang up in Anaheim, Walt regretted not purchasing more land around Disneyland to keep the park an immersive experience; he would not make the same mistake twice. He used many empty business names and pseudonyms to purchase land in Florida for less than $100 an acre before anyone realized what he was doing. Once the news was out that Disney was buying Floridian land, the cost rose by about 1000% and some of the last acres cost $80,000. Following the purchase, the first thing Walt did was set aside a 7,500 acre Conservation Area in 1970, which would never be built on. The false businesses and names he used when buying the land can be seen on some of the windows down Main Street U.S.A. in Magic Kingdom.
