This study developed a tourist destination-based model of happiness, in which tourist happiness is assumed to be determined by destination image and service quality via the mediator of tourist satisfaction. This model was tested valid using the data from 1,450 Swiss inbound and domestic tourists in 2015. Based on the model, we computed a total 68 tourist happiness indices that measure tourists’ happiness with Switzerland as the destination. We also computed 136 indices that measure tourist satisfaction and tourism services quality as a supplement to the tourist happiness indices in order to provide a different yet relevant view of destination performance of Switzerland.
