A ship can be the perfect getaway for pairs—if you pick the right one.

Viking Sun

Viking Ocean Cruises is just a few years old, but their adults-only ships have a quiet, sophisticated atmosphere. Picture afternoon tea in the stunning Wintergarden, dinners in Manfredi’s, the gorgeous Italian restaurant onboard, and cocktails in a cozy lounge by a fireplace. Cabins are spacious and comfortable, with heated bathroom floors and verandas as well as complimentary 24-hour room service and WiFi. All of the line’s just-under-1,000-passenger ships are identical, and this one—the newest until Viking Orion launches later this year—sails around the world so you can, say, learn to tango in Buenos Aires or track down those avocado lattes in Melbourne.

Swoon-worthy detail: Use of the spa facilities are complimentary and, best of all, the steam room, snow room, and whirlpools are co-ed.

Regent Seven Seas Explorer

Billed as “the most luxurious ship in the world,” this decadent 750-passenger luxury ship was designed with no expense spared. Restaurants include Pacific Rim, a Pan Asian spot with a spectacular Tibetan prayer wheel at its entrance, as well as Chartreuse, a Modern French restaurant with a bistro-style menu. Since the line is all-inclusive, everything from wine with dinner to cocktails at night, airfare (including business class on international flights) pre-cruise hotel stays, transfers, WiFi, and shore excursions are wrapped into the rate. Best of all, you don’t have to plan for much in advance before your vacation when the line is handling everything for you.

Swoon-worthy detail: Cabins—all suites, and all with verandas—have gorgeous mahogany-lined walk-in closets and marble bathrooms, as well as high thread count, well, everything. We dare you not to hit snooze twice when the sheets are this soft. Here are 14 cruises you should only take in winter.

Crystal Esprit

Crystal Cruises’ smallest ocean-going vessel is a unique experience. At just 62-passengers, this intimate yacht offers a quiet, low-key experience that’s still posh as can be. Instead of stage productions, several restaurants to choose from, and an extravagant pool-side buffet on sea days, you’ll find a piano bar with sing-a-longs and a small elegant pool as well as a marina with watersports and a submarine.

Swoon-worthy detail: Despite the ship’s small size, all of the cabins are suites, and all have butlers. They remember what the two of you like as the cruise progresses, from bringing those peanut butter cookies you raved over yesterday to making sure you have plenty of their gorgeously designed bath products.
