Cruise tourism has expanded to the Asian region, using larger cruise ships to serve new targets. Therefore, ports are one of the most important factors involved. Thus, the objective of this study is aimed at investigating and comparing cruise port management systems between Phuket and Singapore, employing quantitative research methods. The empirical findings showed that the top five biggest gaps regarding two cruise port management examples were port infrastructure, port facility, political stability, cruise tourism policy and cleanliness in rank. The results revealed that port management in Singapore was more efficient than in Phuket in most variables; however, tourism attractions, tourism activity, service providers, value for money, climate/sea conditions, and immigration formalities of Phuket were slightly better than that in Singapore.
