Princess Cruise has set up hot tubs in two cruise ships that will be operated in the Northeast Asia from April. As part of the $30 million cruise ship renewal project, the international cruise operator has installed indoor and outdoor hot tubs on Sun Princess and Diamond Princess, which will be positioned in China, Japan and South Korea soon. The hot tubs with natural materials will offer relaxation on board. Users will also be able to enjoy Asian foods to be provided by a noodle bar and a sushi restaurant which will open their doors along with the launch of the hot tubs. Japanese foods will be added to regular breakfast menus.
