Tourism experiences have been recognised for their power to change peoples’ lives. Termed transformational tourist experiences, these life-changing experiences have been conceptualised in terms of changes to individuals’ well-being, values, and goals. Yet, little is known about the potential of tourism experiences to induce changes in personality. Drawing on a nine-year longitudinal panel study in the Netherlands with 3292 responses from 1803 participants, we examined within-individual, between-occasion associations between vacation frequency, duration, and extraversion. More frequent and longer vacations were associated with increases in extraversion, and that this effect was partially mediated by the experience of meeting new people during vacations. These findings offer preliminary longitudinal evidence that vacation experiences can drive personality change, and position interpersonal novelty as a mechanism of transformation, extending theoretical understandings of personality malleability and the transformative potential of tourism.
