What am I missing? Does the SuperStar Aquarius have any connection at all to known coronavirus patients? The one in Japan was flagged because someone who got off the vessel was later determined to have the virus. But as far as I can tell, the Aquarius goes back and forth between Taiwan and Japan, and currently is no more a source of concern than any random plane coming from Tokyo or London. (Which to be fair, is not zero.)
Cruise itinerary program
SuperStar Aquarius itinerary program is based on Asia cruises (to Japan) leaving from Taiwan. The ship is homeported in Keelung (Taipei City) and offers round-trip itineraries to Naha, Ishigaki Island and Miyakojima Island.
