We've already taken a look at the most over-the-top suites in Vegas. Now, we're heading out to sea to look at the best cruise ship suites that (a lot of) money can buy.

Note that prices are an estimate and vary depending on itinerary.

Queen Mary 2: Grand Duplex Suites
Clocking in at 2,249 square feet, including balcony, the QM2's two-level Grand Duplex Suites (named after British castles, such as Balmoral and Sandringham) include lavish living quarters with a separate dining area and bar, expansive private deck area downstairs, and an upstairs master bedroom. Lucky guests can also make use of two marble baths with separate whirlpool tub and shower, a guest bathroom, and private exercise equipment, all while enjoying the privilege of  priority embarkation and disembarkation, a bottle of champagne and strawberries at embarkation, and butler service. On Cunard ships, where you dine is determined by which class you are traveling in. Guests in the Grand Duplex Suites get to dine on caviar and Champagne in the renowned Queens Grill.

From $18,500 for a seven-night cruise.

Royal Loft Suite on Allure of the Seas 

The most luxurious suite on the Allure, this two-deck space offers more than 1,500 square feet of room and a welcome respite from an otherwise busy ship. Features include a loft-like master bedroom, two whirlpools (including one on the private wraparound balcony), a large living area with baby grand piano, and panoramic views through a 17-foot two-deck wall of glass.
From $18,000 for a seven-night cruise.

Crystal Penthouse with Veranda on the Crystal Serenity

Designed to evoke the glamour of old Hollywood, most staterooms and suites on board the Crystal Serenity boast their own verandas. The cream of the crop, however, is the 1,345 square-foot Crystal Penthouse with Veranda. Features include a separate dining area, master bath with ocean view Jacuzzi, private workout area, and state-of-the-art Bang & Olufsen sound system. Guests can enjoy 24-hour butler service, a welcome bottle of Cristal Champagne upon arrival, and an invitation to the private Captain’s Quarters Cocktail Party.
From $7,300 for a seven-night cruise.

Royal Concierge Suite with Veranda on the Disney Dream and Disney Fantasy

Situated on Deck 12, the nearly 1,781 square-foot Concierge Suites features private verandas with Jacuzzi, patio furniture, deck lighting, Plexiglass railings and dividers, plus, as this is Disney, childproof locks. As a Concierge Guest, you'll also enjoy the benefits of the ship's Concierge level special services and exclusive access to dedicated areas on the ship. Concierge Guests have their own lounge and private entrance to an exclusive Concierge-only sun deck.
From $15,000 for a seven-night cruise.

Wintergarten Suite on Seabourn Odyssey

Decorated with a Scandinavian style in mind and featuring fresh orchids, the 1,097 square-foot Wintergarten Suite has its own glass-enclosed solarium with Jacuzzi and day bed, large windows with ocean views, dining for six, bathroom with whirlpool bathtub, and guest bath. Guests also get an invitation from the Master for a bridge visit when the ship is in port and private car transfers between airport and ship.
