Best for Beach Bums: Caribbean Cruises on a Masted Sailing Ship with Windstar
Windstar Cruises are the perfect way to island-hop.
If spending a day soaking up the sun on white-sand-fringed Caribbean shores sounds like your idea of perfect beach day bliss, factor this into that fantasy: Sailing into port on a massive yacht, billowing white sails overhead.
Windstar Cruises offers guests just such a transporting experience aboard their seven-night Yachtsman's Caribbean itinerary, sailing round-trip from St. Maarten to island locales in Antigua, St. Bart's and the British Virgin Islands, where diversions include snorkeling, beach barbecues, and seaside party-primed overnight stays in port.

Best for Nature Lovers: Galápagos Islands Voyages with Lindblad Expeditions
Remote and enchanting, the Galápagos are a rightful place of pilgrimage for nature and wildlife enthusiasts.
You can follow in Darwin's footsteps on a family-friendly seven-night island-hopper cruise (bookended with overnight hotel stays in Guayaquil, Ecuador) with the pros at Lindblad Expeditions -- in partnership with National Geographic -- including a team of naturalists (with an "undersea specialist") and a photo instructor.
You'll sail the archipelago aboard the newly renovated, 96-guest National Geographic Endeavour ll to set out on active snorkeling, kayaking, paddleboarding and Zodiac excursions, as well as hikes through lava fields, mangroves, highlands and sandy beaches.
En route, expect up-close encounters with wondrous wildlife like penguins, sea lions, giant tortoises, sea turtles, iguanas, blue-footed boobies and whales.
Best for Culture Vultures: China and Tibet Cruisetours with Viking
Viking River Cruises offers Yangtze River sailings as part of their culturally immersive Chinese "cruisetour" products (combining land-based and river cruising components).
You can opt in for their exceptional 16-night Roof of the World itinerary, which pairs a six-night Yangtze River sailing through the scenic Three Gorges region (aboard the 256-passenger Viking Emerald) with a 10-night land-based exploration of cosmopolitan Shanghai, Beijing (with its Forbidden City and nearby Great Wall of China), Xi'an (home to the Terracotta Army) and most remarkably, Lhasa, in Tibet, where guests can experience unforgettable cultural encounters like a home-hosted teatime or observing monks at debate.
Viking River Cruises: Regular departures from April 11 to November 1, 2017; rates from $4,339/person
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.
The all-suite Seabourn Encore carries 600 guests in 300 double-occupancy suites with private verandas.
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.
Best for Romantics: South Pacific Sailing with Paul Gauguin Cruises
Regularly lauded as the world's most romantic cruise line, Paul Gauguin Cruises whisks starry-eyed guests through the dreamy, beachy idylls of the South Pacific.
Romantics can't go wrong with their seven-night island-hopping voyages sailing round-trip from Tahiti to Bora Bora, Moorea, Huahine (in the Society Islands), and the cruise line's private islet at Motu Mahana.
Made-for-two excursions include sunset champagne sailings (on a motorized boat), snorkeling or kayaking in turquoise lagoons (the ship is equipped with a water sports marina), or Polynesian feasts at the line's own motu.
On board the 332-guest m/s Paul Gauguin, guests celebrating their honeymoon or anniversary are treated to special Polynesian blessing ceremonies, too.

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).
