Ruby Princess is a new addition to Princess Cruises's modified Grand class fleet, which currently consists of Crown Princess, Diamond Princess, Sapphire Princess and Emerald Princess. Like all of her Grand Class sisters, the ship also has the "Movies Under the Stars" feature. The ship has a nearly identical design to her sisters, which includes 3 main restaurants, the specialty restaurants Crown Grille and Sabatini's, a Piazza-style atrium, theater, alternative showlounge, 5 pools and many hot tubs, a spa and gym, and other entertainment and dining venues. Unlike the line's earlier Grand Class ships, Ruby Princess will continued the modified Grand Class design with the Skywalkers Night Club moved just aft of the funnel, rather than suspended over the stern. Ruby Princess also was the first to debut a new program called the Ultimate Ship Tour, where guests are given a behind-the-scenes look at what it takes to run a city at sea. Ruby Princess was handed over to Carnival Corporation and Princess Cruises in late October 2008. The maiden voyage took place on November 8, 2008. Ruby Princess' godparents are Trista Sutter and Ryan Sutter, who christened her prior to the maiden voyage. The ship will embark on a series of 7-day Western Caribbean cruises through April 2009, with stops in Ocho Rios, Grand Cayman, Cozumel, and Princess Cays.
