Travel review websites have become important information source for travellers. Given the widespread use of travel review websites among travellers, little research has been conducted to investigate what motivate travellers to use travel review websites. This study investigates travellers’ continuance intention to use travel review websites by integrating three social media related constructs into the IS success model, and empirically test the research model among the Chinese travellers. In this research we found that the perceived enjoyment and curiosity fulfillment determine travelers’ intention to continue using travel review websites together with the two determinants (information quality and system quality) suggested in the IS success model. Finally the implications for research and practices are discussed.
