Prior studies have ignored information inherent in the structure of people's values when investigating their impact on tourism decisions. This study examined how personal values trade-offs along two bipolar values dimensions (self-enhancement versus self-transcendence and openness-to-change versus conservation) impacted young adults’ travel decisions. A two-staged survey of 299 young adults obtained personal values (at time 1) and value-expressive holiday preferences within a theory of planned behaviour (at time 2). Both bipolar values dimensions predicted attitudes, subjective norms and perceived behavioural control towards value-congruent holidays. The total effect of personal values on intentions was larger than that of subjective norms for both dimensions and larger than that of perceived behavioural control for the self-transcendence verses self-enhancement dimension.
