Although length of stay is a relevant variable in destination management, little research has been produced connecting it with tourists' postconsumption behaviour. This research compares the postconsumption behaviour of same day visitors with overnight tourists in a sample of 398 domestic vacationers at two Mediterranean heritageandbeach destinations. Although economic research on length of stay posits that there are destination benefits in longer stays, sameday visitors score higher in most of the postconsumption variables under study. Significant differences arise in hedonic aspects of the tourist experience and destination loyalty. Thus, we propose that length of stay can be used as a segmentation variable. Furthermore, destination management organisations need to consider length of stay when designing tourism policies. The tourist product and communication strategies might be adapted to different vacation durations.
