Overcoming diversity: The marketing of New Orleans as a tourist destination after Hurricane Katrina – an investigation
New Orleans in Louisiana was previously a premier tourism and convention destination; the effects of Hurricane Katrina have wrought havoc on the economy of the city. In the first year after the hurricane, over 100,000 jobs were lost, and the reputation of New Orleans as being problematic in terms of crime plunged even lower. The city is working hard to restore its reputation and its economy and some estimates hold that tourism is almost back to its pre-Katrina level. This study examines the veracity of such statements and considers the city’s future.
