The 1330 Korea Travel Helpline is a public service that provides tourists with customized travel information in order to promote tourism. 1330 Travel Helpline differs from other online tourism information platforms in that users can interact with certified tourism specialists throughout their journey. Furthermore, the service is run by the Korea Tourism Organization. Taking these distinguishing characteristics into account, the purpose of this study is to investigate the factors influencing the service user's information processing process and the tourist's destination visit intention. This study specifically employs the Elaboration Likelihood Model to examine the impact of information quality and source credibility on destination visit intention. Furthermore, using data collected from tourists who have used this service, this paper investigates whether the interaction quality with service representatives acts as a predictor of visit intention. The PLS-SEM approach reveals that interaction with service representatives gives users a social presence, which influences their information processing path positively. Information usefulness and visit intent are significantly influenced by information quality and source credibility. In addition, the research demonstrates that the interaction quality has a mediating effect on both of the central and the peripheral paths. The findings contribute to a better understanding of the live chat service in the context of the hospitality and tourism industries, as well as suggestions for future research.
