This paper explores the relationship between convention attendees’ perception of service quality and their behavioral adjustment. Data were gethered from the self-administered questionnaires of 150 overseas attendees in the four international conventions held in Seoul. The 43 items for measuring convention service quality were developed and grouped into six dimensions. The major findings were that conference programs and physical environments were the most important factors in influencing attendees’ intention to repurchase and to recommend the occasion to others. Authors hope that the results of this study help future convention destination and host organizations in improving service quality considerations enhancing the customer loyalty.
