ABSTRACT
Tourism in general, and in cities in particular, is a growing sector. Much urban tourism, researchers fi nd, is concentrated in well-defi ned areas within the city. Leisure and cultural tourists are spending more of their time in the CTD (central tourist district), an area that usually includes a historic city center as well. Business travelers spend more of their time in the CBD (central business district) and in conference centers. Due to the increasing numbers of tourists, the spatial activities of tourists throughout different parts of urban centers are some of the forces that shape city centers as we know them today.
