Tourist districts are the principal building blocks of urban tourism. Drawing on a unique historical past, or concentrating new entertainment or sports complexes, these spaces have become the destination spots that enable cities to upgrade or even transform their national and international identities. Local governments often work very closely with major corporations and local development interests to take a leading role in shaping the new visitor oriented districts. A key aspect of building this type of city is the development of the physical infrastructure needed to transport, entertain, and provide accommodation for visitors. Th ese expenditures do not simply help cities meet their economic development goals; in many cases they result in the thoroughgoing spatial reorganization of downtowns, outlying neighborhoods, and public facilities. Quite commonly, expanded downtowns and other reconstituted tourism zones, which were once physically dilapidated, with the construction of sports stadiums, convention centers, casinos, and waterfront parks become jewel-like civic showpieces.
