The Regal Princess, a luxury cruise ship owned by Princess Cruises, will debut on 16 May after completing successful sea trials.

The new 141,000-tonne 3,600-passenger ship – sister to the Royal Princess cruise liner which was launched in 2013 – is preparing for its seven-day maiden voyage from Venice to Athens including stops in Corfu, Mykonos and an overnight call in Istanbul.

Constructed in the Fincantieri shipyard in Monfalcone, Italy, the ship will include a Lotus Spa & Enclave. Accessed via the atrium, the spa comprises a hydrotherapy pool and accompanying rain shower. The spa’s treatment rooms offer heated stone therapies, water beds, sensory showers with mood lighting and aromatherapy. Three of the treatment rooms offer a variety of heat-based experiences: a hammam, a calidarium and a laconium – a dry sauna. Products used in therapies are provided by Elemis.

It will also house a full-service salon – including teeth whitening stations, a barber shop and mani-pedi areas in addition to a relaxation room and 18 treatment rooms.

Furthermore, the spa contains a Scrub & Shine Bar, which provides sugar and salt scrubs in addition to two couples’ rooms complete with whirlpools.

Similar to the sister ship, the Royal Princess, the Regal Princess has a large atrium and a cantilevered, glass-enclosed walkway that extends 28ft (8.5m) beyond the ship’s edge and 128ft (39m) over the water. There will also be poolside cabanas, a Princes Live! television studio, a pastry shop and a special private dining experience that surrounds diners in a curtain of light.

Two main differences have been incorporated into the Regal Princess’ design. They include a promenade deck and an aft pool – an outdoor pool near the stern of the boat.

Princess Cruises, part of Carnival Corporation, is a global cruise and tour company operating a fleet of 17 ships. Princess carries 1.7m guests each year to destinations around the globe ranging in length from three to 111 days.
