Summary: Crompton (1992) proposed a model that reflected rational decision-making in which tourists had a high degree of involvement in choosing the tourism destinations to be visited. This model includes a process of narrowing down the sets of tourism destinations; it begins with all of the potential destinations for a trip and continues until the destinations are finally selected. The principle of Crompton’s (1992) model is based on different theoretical considerations. The first is that there are two types of tourism destinations: those of which the tourist is aware and those of which the tourist is unaware. Because no one can choose an unknown destination, this second group of destinations is automatically excluded. The set of known tourism destinations that are not considered for a particular trip includes: ‘foggy’ (destinations that potential consumers do not have enough information about to have a positive or negative opinion), ‘hold’ (destinations the individual is considering, but not at this time), ‘unpleasant personal experience’ and ‘negative external feedback’.
