However, in their rush to capitalize quickly on the economic opportunities that cultural tourism offers, many communities ignore or fail to recognize the inherent problems and disadvantages of cultural tourism. They are unwilling to acknowledge finite limits to the number of visitors that these special places can accommodate without damaging themselves, or that the quality of the experience is the key attraction. Misuse and exploitation have the potential to destroy the very community resources that attract visitors to begin with. In the words of noted tourism expert Arthur Frommer: “If preservation is to be effective, if the warp of our civilization is to be maintained, if even the goals of increased tourism are to be achieved, then we as a nation must step back from extreme marketplace theories.” Mass marketing, for example, can lead to overcrowding historic Main Streets, threatening the unique sense of place that visitors came to experience. Ever-present vendors and shops constantly remind tourists that they have not escaped from the present. And community residents often develop antagonistic attitudes toward the hordes of visitors whose overwhelming presence complicates their daily lives.
