Mariner of the Seas continues the Voyager-class tradition of offering a decent number of balcony cabins. Additionally, there are four other cabins categories -- suites, outsides, insides and the unusual atrium-view (looking onto the Royal Promenade).
Standard inside, ocean-view and balcony cabins are decorated in light, primary colors and feature light-colored woods. All cabins come with convertible twin-to-king beds and flat-screen televisions, offering interactive services like room service ordering (though we found it easier just to pick up the phone), pay-per-view flicks and numerous channels. (Royal Caribbean TV does an outstanding job, featuring everything from news and sports channels to a promenade cam, which shows the action inside the ship.) Other features include a desk/vanity and seating areas with loveseats or full-length couches, some of which fold out.
Cabins with balconies are each equipped with two basic chairs and a small table. The balconies have glass panels.
Cabins have mini-fridges that are minimally stocked with soft drinks and juices; the charges for mini-fridge items are the same as in the bars. We found there was plenty of room to stash our own sodas, but you can ask the room steward to remove the contents if you need more space.
Bathrooms are basic, and only suites have tubs. The showers have wonderful half-round sliding doors, a fabulous improvement over icky, clingy shower curtains. Soap and shampoo are provided. (Suites get mini-bottles of Royal Caribbean's Vitality shampoo, conditioner and lotion.) Hair dryers are located in the vanities, rather than in the bathrooms, and you'll have to hold a button in to keep them turned on while using them.
Mariner of the Seas offers 26 accessible cabins in a variety of categories and sizes (from 256 square feet to 276 square feet). Features include wider doors, closet racks that can be pulled down to lower heights, and accessible showers and toilets. These cabins are set aside for cruise travelers who can prove they need the accessible amenities; the cabins only enter the regular inventory close to the sail date if they haven't sold out by then.
Interior: Interior staterooms come in two varieties: standard (160 square feet) and promenade view (167 square feet). The standard room features a pair of twin beds that convert to a king, as well as two pull-down beds and can sleep up to four cruisers, but the Promenade View interior staterooms each sleep two people, max. Promenade View rooms have windows overlooking the Royal Promenade. They can be loud at night, and you'll want to keep your curtains closed so people can't see in.
Ocean-view: There are three types of ocean-view staterooms: standard (161 square feet), spacious (211 square feet) and ultra-spacious (328 square feet). The standard and spacious sleep up to four, thanks to two twins that convert to a king and a pair of pull-down beds. The Ultra Spacious Ocean View stateroom sleeps up to six, as it also features a double sofa bed.
Balcony: Balcony staterooms come in two types: standard (198 square feet with a 46-square-foot balcony) and spacious (203 square feet with a 42-square-foot-balcony). Both types sleep up to four each, featuring twin beds that convert to a king and either pull-down beds or a double sofa bed.
Junior Suite: Junior Suites sleep one to four passengers, depending on the room. They are 277 square feet with 46-square-foot balconies, and they're basically an expanded version of a standard balcony stateroom, featuring a sitting area with chair and couch, a walk-in closet and a bathroom with a tub. It's the smallest of the suite classes.
Suite: Suites on Mariner of the Seas come in a variety of configurations. All those in suites, except in Junior Suites, are entitled to use the Concierge Lounge (Deck 14), which features a complimentary Continental breakfast and cocktail hour. The concierge on duty handles special requests for reservations -- alternative restaurants, spa, etc. Diamond Plus and Pinnacle Club members of the Crown & Anchor Society can also access the Concierge Lounge.
Grand Suite: These suites come in one- and two-bedroom layouts, each with a sitting area, bar area and bathroom with tub. Suites with one bedroom sleep up to four, and each is 381 square feet with an 88-square-foot balcony. The two-bedroom Grand Suites sleep up to eight and are each 547 square feet with a 192-square-foot balcony.
Royal Suite: The 1,260-square-foot Royal Suite is the ship's prime suite, featuring an elaborately furnished living room -- wet bar, dining table, entertainment center and even a piano -- and a separate bedroom with king bed and its own balcony. The bathroom is spacious and includes a whirlpool tub, separate shower and bidet. The suite's 224-square-foot balcony is furnished with wicker lounge chairs and a dining table.
Owner's Suite: The 506-square-foot Owner's Suites are also luxurious, each with a king bed, living room and dining area. However, these suites are more open, with the sleeping areas separated from the rest of the living quarters by large, rotating flat-screen TVs, rather than actual walls. The balconies (131 square feet), are big enough for a lounge chair.
