Best for Foodies: French Canal Barging in Champagne with French Country Waterways

For many foodies, France is synonymous with fine wines and a first-rate culinary scene.

Aboard the plushly refitted barges of French Country Waterways, which ply the canals of the French countryside at a leisurely pace, no epicurean would be disappointed.

Six-night sailings through the storied Champagne region -- home to Champagne houses like Moët & Chandon and Veuve Clicquot -- incorporate private wine and bubbly tastings and vineyard visits, strolls through medieval villages and old chateaux, and a dinner ashore at the Michelin-starred Les Crayères restaurant.

On board, just eight passengers are pampered by a six-person crew, including a chef who whips up gourmet, four-course, candlelit dinners nightly, paired with regional cheeses and fine wines.

Best for Adventurers: Northwest Passage Crossing with Crystal Cruises

In 2016, the 1,070-passenger Crystal Serenity made headlines for becoming the first large luxury cruise ship to traverse the once-impassable Northwest Passage -- a feat that's been made possible by the continued effects of climate change.

This year once again, Crystal's most intrepid guests -- and those with 32 vacation days and a pretty penny to spare -- will be able to make the one-off sailing through this frigid Arctic region between the Pacific and Atlantic Oceans (from Anchorage to NYC).

En route, cruisers can count on Arctic expert-accompanied encounters (sometimes by kayak, Zodiac boat, or even helicopter) with this far-flung locale's glaciers, fjords, tundras, Arctic communities, and rarely spotted wildlife, including polar bears, caribou and whales.

Solo cruisegoers used to have to pay extra fees, but those days are over.

Norwegian Cruise Line's 4,100-passenger Norwegian Epic pioneered an industry-first cruise market for solo travelers, thanks to its designed (and priced)-for-one Studio staterooms (with 128 available), as well as a private Studio Lounge where fellow solo travelers can meet up over coffee and conversation on board.

You can mingle with other singles while sailing its seven-night Mediterranean itinerary, taking in solo-friendly ports in happening European cities such as Barcelona and Rome, as well as more Med stops primed for solo-friendly activities like beach-lounging or taking in world-class art museums (including Naples, Florence, Cannes, and Majorca).
