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.

Queens is the most ethnically diverse area of its size on Earth, which means there's a little something for everyone. Chow down on Indian food, sit in on a traditional Irish pub music session, and dance the night away at a Puerto Rican nightclub, all of it located within a few subway stops. Queens is also the home of the Mets and the US Tennis Open, and the former home of the New York World's Fair, now Flushing Meadow-Corona Park, and Paramount Pictures, now the Museum of the Moving Image.

Newark has been welcoming guests since its first hotel opened in 1670. From the largest number of cherry blossoms in the U.S. to one of the country's highest grossing arenas, from Shaquille O'Neal's supersized cinema to the biggest collection of Tibetan art outside Southeast Asia, it's all still happening in Newark. Just eight miles from New York City, Newark offers travelers quick access and easy connections. Jump in and discover pro sports, fine arts, urban retail and outdoor adventure.

Famous as the home of Yankee Stadium, elevated trains, and dense apartment blocks, the Bronx is also the greenest of New York City's boroughs. Visit the gorillas at the famous Bronx Zoo or wander through the 50-acre forest at the New York Botanical Garden. Pick up some gourmet foods on Arthur Avenue, the Bronx's Little Italy, and have a picnic at Van Cortlandt Park, which features two square miles of boating, horseback riding, tennis, and the oldest public golf course in the United States.

The most suburban of the five boroughs, Staten Island is often neglected as a tourist destination. Take a ride from Manhattan on the Staten Island Ferry and get some of the best views of New York City for free, then stick around and see what Staten Island has to offer. Check out the Himalayan monastery-style Jacques Marchais Museum of Tibetan Art, or visit Historic Richmond Town for a recreation of colonial New York. The beautiful Hamilton Park neighborhood was the setting for "The Godfather."

Walk the Freedom Trail the first time you visit Boston and you'll quickly get a sense of this coastal city's revolutionary spirit and history. But make sure you also explore some of Boston's fine museums (try the Isabella Stewart Gardner, featuring masterpieces displayed in their collector's mansion) and old neighborhoods (like the North End, Boston's Little Italy). You can't claim to have experienced real Boston culture, though, until you've watched a Red Sox game from the bleachers.

The windy city is a cornucopia of modern art, fine dining, cutting edge comedy, and die-hard sports fans. Snap a photo of your reflection in the silver Cloud Gate sculpture at Millennium Park before heading to Grant Park to get hit with the refreshing spray of Buckingham Fountain. There are dozens of museums and theater companies in Chicago, so a cultural experience is never hard to find. You’re sure to laugh your head off at the Second City Theater, the professional launch pad of many famous comedians.

Whether you’re a high roller or a low-key lounger, Las Vegas has something to suit your vacation taste. Sample fare from top chefs and cornucopian buffets, try your luck at one of the world’s premier casinos, or take in a spectacular show. Just wandering the Strip is enough to get your heart pumping. Once you’ve had enough of the razzle-dazzle, wave hello to the toothy sea life at the Mandalay Bay Shark Reef, hike Red Rock Canyon, or visit the Neon Museum, where old signs take on new life.

Hollywood beckons to tourists who long for a brush with Tinseltown glamor. Tour movie studios, slip your hands into the famous prints at the TCL Chinese Theatre, or indulge in a celeb sighting at one of LA’s white-hot nightspots. Spot your favorite star while shopping at The Grove, or forget all about the famous eye candy as you take in the iconic artwork at The Getty Center. For a different type of star-gazing, peek through the telescopes at the Griffith Observatory.

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.

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.

This city, full of colorful homes, canals and bridges, is one of Europe's most picturesque capitals. Must-sees on any visitor's itinerary include the Anne Frank House, the Van Gogh Museum and the world's only floating flower market. Rent a bike and join thousands of locals navigating Amsterdam's labyrinthine streets, or just take in the sights on foot. For an unusual and memorable alternative to hotels, consider staying in a houseboat.

Barcelona feels a bit surreal – appropriate, since Salvador Dali spent time here and Spanish Catalan architect Antoni Gaudí designed several of the city’s buildings. Stepping into Gaudí’s Church of the Sacred Family is a bit like falling through the looking glass - a journey that you can continue with a visit to Park Güell. Sip sangria at a sidewalk café in Las Ramblas while watching flamboyant street performers, then create your own moveable feast by floating from tapas bar to tapas bar.

One of the world’s fashion capitals, Milan offers endless opportunities for chic shopping. Hit the artsy neighborhood of Brera for leather goods and Via Monte Napoleone for exclusive, expensive boutiques. The enchanting mosaics and glass vaults of Galleria Vittorio Emanuele II make shoppers feel like they’re wandering inside a painting. Take break from your spree to gape at the iconic Duomo, then grab tickets to a performance at La Scala. Post-opera, the Navigli district pulses with late-night activity.

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.
