Central Florida boasts one of the largest concentrations of theme parks in the world. Disney World, the industry’s dominant firm, has the two largest theme parks (EPCOT Center and Magic Kingdom), each drawing over 80% of all Central Florida tourists who visit at least one theme park (Florida Division of Tourism, 1987). However, within a 70 mile radius of the Disney theme parks, there are over 20 additional parks. Table 1 shows the percentage of tourists who visit each of the area’s eight largest parks. The purpose of this paper is to test the hypothesis that unit savings costs that accrue to customers through the decrease in the real costs of time and travel is an important factor in explaining agglomeration of the industry.
