The concept of the crowding-out effect has been employed in the tourism literature to analyse complex phenomena. However, there is limited insight into the crowding-out effect on tourists by tourists, and even less into the impact of distance on the crowding-out of tourists. This paper examines the relationship between crowding perceptions, tourists' attitudes toward crowding and the consequences of being crowded out. Results from a sample of 729 international tourists in Hong Kong suggest that there is a crowding-out effect on tourists by tourists, but this has only a marginal influence on the majority. The limited crowding-out effect is induced by tourists in general rather than by a single segment. The study also investigates the effect of distance on tourist crowding. The findings reveal a decaying effect of distance on tourists’ crowding perceptions, as neighbour tourists are more susceptible to tourist crowding than tourists from long-haul markets.
