Cruise data are scarce and not homogenous. The best data bases are from North
America, the Caribbean and Oceania. For destinations outside the Americas and Oceania
it is, even, very difficult to approximate the number of cruise passengers. This is the
reason why most of the empirical studies refer to destinations in those mentioned regions.
The paper by Ikeda and Jaswar (2002) present a prediction method of travel demand of
cruise ships in Japan. It is one the few empirical studies using data from an Asian
destination.
