Conventions bring a huge economic impact to cities. Many cities are making an effort to host conventions. As a result, competitions for inviting conventions between cities are fierce. In marketing cities as convention's destination, it is indispensable to increase the attractiveness of the destination itself. The objective of this study is to investigate the determinants of customer satisfaction with the convention host city. Using a convention attendees' empirical data, we develop a structural equation model explaining customer satisfaction with the convention host city. The study found that 4 factors; “encountering special local food and souvenirs”, “reputation of convention facility”, “attractiveness of sightseeing”, and “accessibility to the convention site” are the key points to improve attendees' customer satisfaction level. Also the study clarified that improved attendees' customer satisfaction level is directly linked to higher intention of revisiting and reputation as a convention host city.
