It is tipped to be most decadent ship at sea – Regent’s Seven Seas Explorer will debut next year and Cruise Passenger brings you a sneak peek into the Penthouse suites.

The 750-guest, all suite, all-balcony ship has five Penthouse Suites, each with an expansive balcony that spans nearly 10 feet.

The suites’ handcrafted, custom-made furnishings are in brilliant blue accents, which the line says are inspired by sapphires.

The Penthouse cabins range up to 626 square feet and feature and entertainment centre that is separate from the living room and bedroom, a marble-topped bar, a dining area and a decadent bathroom.

The 140 Concierge Suites are inspired by vacation homes found in Cape Code on the eastern seaboard of the USA.

Each Concierge Suite measures up to 460 square feet and features a European king-sized bed which faces out to the ocean.

But if you want to splash some cash, the Seven Seas Explorer’s top accommodation is the 3,875 square-foot, two-bedroom Regent Suite (but that excludes the 1,000 square foot wraparound balcony).

This suite stretches across the width of the ship and has a grand piano and an enclosed sunroom.

The lucky guests will also have an ensuite spa with a sauna, steam room and private treatment area.

But at around US$5,000 per person, per night, start saving!
