Novelty, conceptualized as the experience of something new and different from the everyday, is widely believed to be what defines tourism experiences and makes them enjoyable. The present study tests the mediating effect of novelty on positive emotions in two longitudinal data sets based on daily psychometric diaries. Findings show that the effect of tourism experience on positive emotions is indeed partly mediated by novelty. The mediation effect is similar for average positive emotions as well as for the emotion of interest, suggesting that novelty sparks positive emotions through goal congruence more than by directly triggering interest. Findings affirm that novelty is indeed fundamental and enjoyable in the tourism experience.
