The smallest of the Trójmiasto (Tri-Cities), the Baltic Sea spa town of Sopot is smack between Gdansk and Gdynia, just a few miles from each. A retreat for the rich and royal for centuries, Sopot’s exclusive air remained even through the Communist era, and the tony town has undergone a building boom in recent years. Boasting beautiful beaches and ritzy resorts, Sopot is also known for its Wooden Pier (the longest in Europe), the lovely mid-woods Forest Opera and lively Monte Cassino Street.

One of Poland’s most beautiful cities, Gdansk, on the Baltic Sea, has played major roles in history, especially in the 20th-century. It was the 1939 flash point of World War II, and then in 1980, the birthplace of the Solidarnosc labor movement, ushering the end of Communist domination in Eastern Europe. Gdansk’s Old Town, painstakingly reconstructed to its Hanseatic League glory after being leveled in World War II, is a highlight. The 14th-century Town Hall houses the city’s historical museum.

In Vienna, the coffee house isn’t just a hangout: it’s an institution. Lingering over a newspaper with a pastry and a strong espresso drink is, according to UNESCO, officially a Viennese cultural pastime. Walk off your slice of Sachertorte with a self-guided tour of the city’s stunning traditional, Secessionist, and modern architecture, such as the Imperial Palace, the State Opera House, the Kirche am Steinhof, or the Kunsthistorisches Museum, an exercise in ornate geometry.

Situated on the Dutch border, Limburg is the easternmost province in Flanders, and the foremost fruit-growing region in the country. The lively, friendly market town of Hasselt is the provincial capital. It boasts a car-free historic center, with building dating back as far as the 11th century. Genk is another recommended stop. The city of 63,000 people is home to a zoo, a planetarium, De Maten nature reserve and Bokrijk, an open-air museum of 19th century Flemish architecture.

Lingering over pain au chocolat in a sidewalk café, relaxing after a day of strolling along the Seine and marveling at icons like the Eiffel Tower and the Arc de Triomphe… the perfect Paris experience combines leisure and liveliness with enough time to savor both an exquisite meal and exhibits at the Louvre. Awaken your spirit at Notre Dame, bargain hunt at the Marché aux Puces de Montreuil or for goodies at the Marché Biologique Raspail, then cap it all off with a risqué show at the Moulin Rouge.

From Shoreditch’s swaggering style to Camden’s punky vibe and chic Portobello Road, London is many worlds in one. The city’s energy means that no two days are the same. Explore royal or historic sites, tick off landmarks from your bucket list, eat and drink in exclusive Michelin-starred restaurants, enjoy a pint in a traditional pub, or get lost down winding cobbled streets and see what you stumble across – when it comes to London, the possibilities are endless.

Rome wasn't built in a day--and you'll need much more than a day to take in this timeless city. The city is a real-life collage of piazzas, open-air markets, and astonishing historic sites. Toss a coin into the Trevi Fountain, contemplate the Colosseum and the Pantheon, and sample a perfect espresso or gelato before spending an afternoon shopping at the Campo de’Fiori or Via Veneto. Enjoy some of the most memorable meals of your life here, too, from fresh pasta to succulent fried artichokes or a tender oxtail stew.

Dubai is a destination that mixes modern culture with history, adventure with world-class shopping and entertainment. Catch a show at the Dubai Opera, see downtown from atop the Burj Khalifa and spend an afternoon along Dubai Creek exploring the gold, textile and spice souks. If you’re looking for thrills, you can float above the desert dunes in a hot air balloon, climb aboard a high-speed ride at IMG Worlds of Adventure or skydive over the Palm Jumeirah.

Conquering New York in one visit is impossible. Instead, hit the must-sees – the Empire State Building, the Statue of Liberty, Central Park, the Metropolitan Museum of Art – and then explore off the beaten path with visits to The Cloisters or one of the city’s libraries. Indulge in the bohemian shops of the West Village or the fine dining of the Upper West Side. The bustling marketplace inside of Grand Central Station gives you a literal taste of the best the city has to offer.
