This study explores demographic characteristics and travel patterns of two different groups of Chinese tourists, casino and non-casino visitors to South Korea. The homogeneity analysis shows that significantly differentiated characteristics are found between the above groups. That is, casino visitors are characterized by those with low education but with high income carrying much travel budget themselves, with much experiences in overseas travel, and accompanied by family or relatives. The other party showed the profile of high education, relatively little overseas travel experience, low income, low travel budget, and traveling with peer groups. The result may help casino marketers establish effective marketing strategies to the target groups.
