The main focus of this research is to investigate how international tourists cope with negative tourist-to-tourist encounter conflict and co-create better traveling experience when traveling abroad by using the Critical Incident Technique. Tourist experiences are explored in social (tourists to tourists / industry personnel/ local residents) and physical encounter. The study samples were twenty inbound tourists coming to Taiwan for long term travel around three months. Study volunteers must recode the critical incident events for each trip as a traveling diary, and then participate in in-depth interview afterwards. All data would be analyzed by using Content Analysis. Methodological Triangulation will be used to enhance the reliability and ability of this study. The research found ten different coping strategies from emotional to behavioral strategies used by tourists with different gender and nationality background. Besides around twelve co-creating strategies which involved the joint cooperation among tourists and other tourist, industry personnel or local residents were also identified to increase the better traveling environment and value.
