During their trips, it is common for tourists to select their places to stay overnight. Nevertheless, along with the diversification of choices at present, tourists also select casinos, saunas, and karaoke bars. In other words, a commercial establishment may not be the default choice from the perspective of tourists. This study examines the factors that affect the accommodation/overnight stay choices of tourists in Macau and investigates the effects of the four aspects of market segmentation namely, demographics, geographic regions, psychographics, and behavioural patterns. The findings showed that they significantly affect the places that tourists select stay overnight, with geographic regions having the strongest effect. A revised model is also proposed.
