Every cabin onboard Mariner includes a balcony, so there's no such thing as a bad view, and all cabins are spacious and comfortably laid out. The top-level suites were refurbished in 2014 and look new and modern, with a stylish color scheme and sleek marble. Lower-level suites didn't receive the same attention, though, and, while large and comfortable, they look somewhat dated.
Each cabin includes a European king-sized bed that can also be configured as two twins, a seating area with couch, small glass table and a chair, an ottoman, a desk with plenty of drawers, two nightstands, a vanity, cabinets for bar glasses, a flat-screen TV (with 20 channels and free movies on demand), DVD player, safe and walk-in closet. Storage is plentiful, with lots of drawers and extensive closet space, though we could have used a few more hangers. A curtain can be drawn to divide the bed from the seating area.
Bathrooms include marble basins, toilets and bathtub/shower combinations, as well as glass shelving for storing toiletries. Bathtubs are deep, with handrails along both sides to assist passengers as they get in and out. The shower is otherwise a little tight; tall passengers will have to duck to get under the water and low ceiling. Toiletries include L'Occitane products (shampoo, conditioner, bar soap, shower gel, lotion and an effervescent bath cube) and shower caps.
Balconies vary in size depending on cabin category, but all include at least two large padded wicker chairs, which can recline, and a small wicker table suitably sized for holding drinks or an ice bucket.
As one might expect from a luxury line like Regent Seven Seas, the amenities and details are exceptional. Passengers in all cabin levels get a welcome bottle of Champagne, fresh fruit replenished daily, complimentary shoe shine service, 24-hour room service (including a dinner service, where meals are served course by course), sewing kits and a free, personalized refrigerated mini-bar setup that's refilled each day with soda, beer, tonic and water. You'll also get a personalized liquor setup. Other cabin amenities include wine and bar glasses, hair dryers, bathrobes and slippers, umbrellas and shoehorns.
The smallest cabins on Mariner are the Deluxe Veranda Suites, which come in at 252 square feet, with 49-square-foot balconies. Cabins in this category, along with Concierge Suites, are decorated in shades of orange, brown and cream, with dark-wood furniture and accents like chair rails and mirror frames. Concierge Suites are sized the same but include a few extra perks, such as binoculars, illy coffeemakers and cashmere blankets to make sitting on the balcony more comfortable when it's cool. Passengers in these suites also get free Wi-Fi (200 minutes for cruises of one to seven nights; 300 minutes for eight to 10 nights; 400 minutes for 11 to 15 nights; 500 minutes for 16 nights or more). These perks also apply to the other higher-level suites.
Passengers staying in Penthouse Suites are treated to larger cabins and balconies (376 square feet with 73-square-foot balconies), as well as additional perks, including a variety of Hermes and L'Occitane soaps, shampoos and lotions; iPhone docking stations; complimentary use of iPads and iPods; and daily canapes. Cabins in this category and above feature soft gray and light beige decor. Horizon Suites, located at the back of the ship (359 square feet), feature massive balconies (268 square feet each).
Seven Seas Suites feature all the amenities provided to the lower cabin categories, and passengers are assigned butlers, who can make reservations at the restaurants, assist with unpacking and repacking, and even draw baths. The Seven Seas Suites located at the front of the ship are slightly smaller (505 square feet) than those located at the back (561), and the balconies for those forward suites are significantly smaller (97 square feet versus 286).
Each of the six Mariner Suites (650 square feet, 89-square-foot balconies) features a true bedroom separated from a large living room. Each also includes a full bathroom, plus a half-bath. Passengers who stay in this cabin level and above are guaranteed reservations each night in one of Mariner's complimentary specialty restaurants, either Signatures or Prime 7.
The ship also has two Grand Suites (903 square feet, 84-square-foot balconies); each includes a separate bedroom, sizeable living room with large picture windows and two full bathrooms. Each of the two 1,204-square-foot Master Suites can accommodate up to five passengers and includes two bedrooms, two full baths, a large living room and two balconies -- a 71-square-foot side balcony off one bedroom and a 727-square-foot front balcony adjacent to the living room and other bedroom.
Six cabins are available with facilities for disabled passengers, and several suites feature walk-in shower stalls.
