Tourism is the growing economy of this millennium. Tourists have a very large variety of fascinating places around the globe which can be easily visited with the growing accessibility and the change in the global economy. This means that tourism planning must be much more sophisticated than in the past. Based on a thorough study of the existing and potential tourists to a specific area or site, unique tourism development must be planned. The main keys for success are usually uniqueness and diversity. Similar things can be said about the planning of leisure time activities within cities or metropolitan areas.
