CARNIVAL/TNS After years in development, Carnival debuted its Ocean Medallion technology on a Princess Cruises ship late last year. That includes thousands of sensors installed aboard its Medallion-class Princess Cruises ships, Caribbean Princess and Regal Princess, and later this year, Royal Princess, Crown Princess, and Sky Princess. Although passenger launch was originally targeted for November 2017, the Ocean Medallion technology didn't fully roll out until late last year. We sailed on a recent Caribbean Princess cruise to test Ocean Medallion and talk with passengers about it. On select ships, passengers can also use the app to control their cabins' air conditioning, heating, blinds and TV.
