Specifically, it uses cluster analysis to identify and profile particular segment groups of travelers to major Mediterranean sun-and-sand destinations based on their novelty-seeking behavior. The aim is to examine whether travelers' novelty-seeking behavior affects their likelihood to return to the destination.
