Cultural heritage tourism is still the growing segment of tourism industry. Moreover, many tourists prefer exploring something new, cultural heritage tourism (CHT) has become one of the major "new" segments of tourism demand. Therefore, it is true that cultural heritage tourism has been one of the major sources of both quantitative and qualitative growth of tourism industry in many countries. In regard to the context of cultural heritage tourism industry, by identifying the relationship and impacts between tourist motivations, tourist satisfaction, and overall sense of tourist well-being, tourism marketers and administrators who are engaged in cultural heritage tourism can improve strategies for creating tourist's distinctive experiences, allowing tourists to become more physically and emotionally engaged in cultural heritage tourism destinations. However, there is, if any, very limited work that explores the link between cultural heritage tourism experiences and overall sense of tourist well-being induced by these experiences. Therefore, this study examines what attributes on tourist motivation contribute to the overall sense of well-being of tourists who visit cultural heritage tourism destinations. Therefore, this study examines what attributes on tourist motivations contribute to the satisfaction and the overall sense of well-being of tourists who visit cultural heritage tourism sites. An online survey using panel data from a marketing research company was used to collect 350 completed questionnaires. Tourist motivations (HONs and LONs), tourist satisfaction, and overall sense of tourist well-being were measured using different scales from previous researches discussed in the literature review. This study conducted various analyses including a profile of 350 respondents based on descriptive statistics, exploratory factor analysis of tourist motivations, correlation analysis of all constructs, and path analysis for the conceptual study model to understand the relationships between tourist motivations and tourist satisfaction, tourist motivations and overall sense of tourist well-being, and tourist satisfaction and overall sense of tourist well-being and identify impacts of each construct on the study model. This study contributes to the growing body of knowledge in understanding the link between cultural heritage tourism and overall sense of tourist well-being and identifying the perceived value and critical role of tourist motivations and tourist satisfaction connecting to overall sense of tourist well-being by establishing a theory based on empirical link between tourist motivations and overall sense of tourist well-being via tourist satisfaction in the context of cultural heritage tourism business. / Master of Science
