The Royal Princess maiden season cruises will open for sale on March 15, 2012. There will also be two three-day preview cruises sailing roundtrip from Southampton on June 10 and 13 that will be available for booking at a later date. "It's fitting that our new ship will cruise on our most popular Europe itinerary, the Grand Mediterranean," said Jan Swartz, executive vice president for Princess Cruises. "And the shorter preview cruises prior to the Mediterranean season certainly offer a unique opportunity to sample the new Royal Princess experience our passengers are eagerly awaiting." Also revealed today were more details about the ship's atrium and its vibrant collection of always-changing quick bites and light meals, beverages, entertainment, shopping and guest services. This signature space will be 50 percent larger than on the newest class of Princess ships and will debut a number of brand new features, including Bellini's Italian cocktail bar, Ocean Terrace seafood bar, a gelateria, and Celebrations, a new gift shop for those marking special occasions onboard.
