ABSTRACT. In marketing research, tourism scholars have often developed a variety of scales and integrated them into segmentation studies. Since vacation lifestyle variables, which could be utilized as a base for marketing research, have not received much attention from market researchers, this article attempts to further purify the extant scale and use Taiwanese travelers as a case study. The study survey was conducted of 443 tourists staying at least one night at the KenTing National Park in Taiwan from April to May, 2002. This study collected 420 useful samples. Three groups of users merged from the cluster analysis: (a) Family Oriented Travelers, (b) Social Oriented Travelers, and (c) Stylish Travelers. The study shows that the differences in trip characteristics are the frequencies of domestic travel, the frequencies of international travel, the hotel preferences, and the average expenditure on accommodations. The variations in demographic characteristics relate to age, family life cycle, education, and household income. This study on vacation lifestyle subsequently renders a new assessment tool to tourism professionals in Taiwan to grasp the lifestyle profile of their customers and develop strategies to entice the travel market.
