TPG Contributor Adam Erace shares his picks for some of the most luxurious cruises around the world.The World Floating Residence: It’s not just a boat, it’s a lifestyle.The WorldDon’t call it a cruise ship. No, seriously, don’t — the World’s publicists think it’s confusing to refer to the luxurious colony of floating residences they represent as such. The World is a boat, or rather, it exists on a boat that’s been traveling on water and visiting exotic ports like any other cruise ship since 2012. But the World is more a lifestyle than a self-contained vacation — albeit one for the fabulously wealthy, who purchase/rent 165 plush apartments with private verandas, framed art, marble bathrooms, etc. for yearlong hop-on/hop-off itineraries. The World’s 2015 journey began in Singapore and will wrap with winter holidays in Antarctica.Rewards Program: Ha. Though you could conceivably use the Capital One Venture Rewards Credit Card, Barclaycard Arrival Plus World Elite Mastercard, American Express Blue Sky or Chase Sapphire Preferred card for statement credits toward your floating mansion.Co-branded Credit Card: NoneRobot bartenders make drinks aboard the Anthem of the Seas.Royal Caribbean Anthem of the SeasRoyal Caribbean milked the press circuit last year with the premier of its new Quantum Class boat, Quantum of the Seas, a ship kitted out with headline-ready amenities such as robot bartenders, bumper cars and an observation globe cantilevered over the waves. Its sister ship, the 2,090-stateroom Anthem of the Seas, was christened in April, making it the youngest in this award-winning line. Anthem is spending its summer sailing through the Mediterranean, Northern Europe and the Canaries, then repositions to Cape Liberty, New Jersey for Caribbean sailings this fall.Rewards Program: Crown & Anchor Society, MyCruise Rewards allianceSign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.

If you prefer your adventures on your plate, Norwegian ups its game here with outlets from Miami’s Pubbelly group, the Mondavi family, Jimmy Buffet and Iron Chef Jose Garces. Garces’ Bayamo occupies a part of the Escape called the Waterfront, a first-at-sea quarter-mile promenade that lets passengers dine al fresco. Escape begins sailing year-round Caribbean itineraries starting in November.Rewards Program: Latitudes RewardsCo-branded Card: Norwegian Cruise Lines World MasterCardThe Viking Star pool deck.Viking StarSince its founding in 1997, Viking has made Europe’s rivers its dominion. That’s all about to change with the debut of the Viking Star, the first vessel in the company’s new oceangoing division. Star accommodates 928 passengers in Scandinavian-inspired staterooms that start at 270 square feet (large for cruise ships) and all feature private verandahs. Outside the rooms, you’ll find dignified Downton-ish pleasures (chef’s table tasting menus with wine pairings, afternoon tea in the Winter Garden, a snow grotto in the spa) but what’s really exciting is the pool, which has a retractable roof and infinity edge that makes you feel like you’re swimming in the Mediterranean. Star departed Istanbul for Venice last month on her maiden voyage; she’ll spend the rest of the year sailing around Scandinavia and Western Europe. Two sister ships are already on order.Rewards Program: Referral Rewards, Explorer SocietyCo-branded Card: NoneLounge on the Britannia.P&O BritanniaDance classes, eyelash extensions, cooking lessons from British celebrity chef James Martin and art walks through Britain’s largest floating art collection (6,000+ pieces) are just a few of the diversions on P&O’s 3,600-passenger Britannia, which made her maiden voyage in March from Southampton through the Mediterranean. Grown-ups will love the ship’s comprehensive kids’ club, as well as adults-only zones such as the VIP-access Retreat, an al-fresco hideaway off the immaculate Oasis Spa, and the Serenity Pool flanked by marshmallow loungers and shaded cabanas.Rewards Program: Peninsular ClubCo-branded Card: NoneThe Explorer.Regent Seven Seas ExplorerRegent is calling its upcoming 750-passenger Explorer the Most Luxurious Ship in the World™ — no small claim. However, it’s walking the walk with ooh-la-la trappings including rare Breton blue lobster at the French restaurant, pool attendants who will polish your sunglasses, a Canyon Ranch spa and state-of-the-art kitchen for culinary classes. But where Explorer will really stand out is the Regent Suite, a 3,875-square-foot palace-at-sea: think wraparound balcony, 270-degree bow views, in-suite sauna and steam, butler, Hermes amenities, grand piano and 1980s-mobster amounts of gold and marble. The price is more than $60,000 per person on Explorer’s 14-night Monte Carlo-to-Venice route… but at least business-class airfare is included.Rewards Program: Seven Seas SocietyCo-branded Card: NoneBe sure to see these related posts:Maximizing Points and Miles With CruisesWhat Credit Card Is Best For Cruises?United MileagePlus Offers Cruise Redemption OptionsCelebrity Cruises Captain’s Club – Loyalty on the High SeasPlanning to hop aboard any of these ships this year, or take another cruise?
