The Sphere-class vessel will accommodate 4,300 guests and offer panoramic ocean views, "innovative" entertainment venues, multi-storey dining rooms and a class of staterooms.
Currently under construction at the Fincantieri shipyard and scheduled to debut in February 2024, the 175,500-tonne vessel "embraces Italian heritage" by featuring the brand’s well-known Piazza and new feature The Dome – an entertainment space inspired by the terraces of Santorini.
Sun Princess will sail an inaugural spring/summer season of Mediterranean cruises from February 2024 followed by Western and Eastern Caribbean voyages out of Port Everglades, Florida in autumn 2024.
The ship’s first three voyages will go on sale on Friday 16 September. Fares start from £1,789pp for a 10-night Grand Mediterranean voyage, departing 28 February 2024.
John Padgett, Princess Cruises president, said: "Sun Princess is a new and bespoke ship platform, designed to simultaneously embrace Princess heritage while boldly pressing into the future with iconic, elegant and pure lines unique to our brand.
"A show-stopping, first-of-its-kind Dome on the top deck and suspended glass Piazza in the centre of Sun Princess offer innovative designs showcasing expansive ocean views for incredible opportunities to connect with the sea."
The ship will offer more than 29 dining and bar options, the three-storey Piazza, a new coffee shop, and popular brand spots such as Crooners Bar, Bellini’s Cocktail Bar, and Alfredo’s Pizzeria.
The Dome is a multi-level covered deck and, according to the line, the first-of-its-kind glass-enclosed dome to be constructed on a cruise ship.
During the day, The Dome features an indoor/outdoor pool and a water feature. At night, the pool becomes a stage, and The Dome transforms into an entertainment venue with lighting effects and the ability to deliver aerial performances.
With 2,157 total staterooms, including 50 suites and 100 connecting rooms, the 21-deck Sun Princess features more outdoor balcony space and all balcony accommodations feature an in-room sofa.
Also launching exclusively on Sun Princess will be a new level of suite accommodations, the Signature Collection.
In addition to premium stateroom amenities, Signature Collection suites include access to the Signature Restaurant, Signature Lounge, and Signature Sun Deck, a private area of The Sanctuary.
Club Class accommodations onboard Sun Princess, and all other Princess ships, will now be called Reserve Collection, which are the best-located mini suite staterooms.
Sun Princess is part of Carnival Corporation’s green cruising focus and is one of 11 new ships in the corporate fleet powered by liquefied natural gas (LNG).
