Princess has announced that Sapphire Princess will homeport in Shanghai for 4 months starting in May 2014.
The 2014 China season will feature four different itineraries ranging from three to seven days, which their research showed fit the emerging Chinese vacation market.
The seven-day itinerary will take passengers to Seoul, South Korea, the beach resort of Busan and finish at the island of Jeju before returning to Shanghai. The five-day cruise will call at Jeju and Inchon, and the four-day itinerary will call at Busan and Jeju. The three-day cruise calls at Jeju.
Princess recently opened several offices in China so I would expect to hear more reports of cruises homeporting in China, perhaps sooner rather than later.
