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.

Southwest of London is Southampton (Soton to the locals), a metropolitan area centered around the port. However, tucked away on the side streets are ancient gems such as the Tudor House, Mottisfont Abbey, and "God's House," a museum located in a tower in the medieval wall. The ultra-modern Sea City Museum celebrates Southampton's seafaring past and the RMS Titanic. Looking for nightlife? Travelers can dance the hours away with bars, clubs, and live music, all accessible by public transportation.

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.

For an unusual and memorable alternative to hotels, consider staying in a houseboat.

Once known for smog, traffic and tacky architecture, Athens is a city reformed thanks to fortunes brought by the 2004 Summer Olympics. Spotless parks and streets, an ultra-modern subway, new freeways, an accessible airport and all signs in perfect English make the city easily negotiable. Meriting more than a stopover en route to the islands, sophisticated Athens sites include many pillars of Western history, from the Acropolis to the Temple of Olympian Zeus, as well as treasures in the National Archaeological Museum.

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.

It seems like most folks have a grandmother, great-uncle or some other distant relative that used to live in Brooklyn, or perhaps a friend that lives there now. In the early 1900s, it was a mecca for immigrants arriving via Ellis Island. A hundred years later, young professionals and artists left pricey Manhattan digs for Brooklyn's cheaper and more expansive space. Neighborhoods like Brooklyn Heights and Park Slope, which had fallen into disrepair over the years, were restored and reborn as funky enclaves. Walk or bike over the historic Brooklyn Bridge (or ride the subway) to Brooklyn Heights for a stroll along the Promenade and breathtaking views of the Manhattan skyline. Meander through Prospect Park and the Brooklyn Botanical Gardens for a taste of nature in the urban wilds. Catch a performance at the world-famous Brooklyn Academy of Music. From the delicious Italian restaurants of Bensonhurst to the Irish bars that line the avenues of Bay Ridge, from the hotdogs and rollercoasters of Coney Island to the bagels and handball courts of Greenpoint, Brooklyn is a state of mind as well as a dynamic community. Discover why, no matter where people move on to, they remain Brooklynites at heart.

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.

Fort Lauderdale’s canals and charm have earned it the nickname “The Venice of America.” The beaches offer 23 miles of golden sand, lively with the spirited antics of happy vacationers.

Shopping and dining al fresco on Las Olas Boulevard is one of Fort Lauderdale’s greatest pleasures, thanks to adorable shops and prime people-watching.

Miami is hot hot hot! And it’s not just the sultry weather. Here, the nightlife is scorching, thanks to a strong Latin influence and spicy salsa culture. Dance the noche away in a nightclub, or indulge in a fancy meal at one of the city’s celebrity-owned restaurants. By day, hit the beach of course, or have yourself a walkabout, taking in Miami’s colorful art deco architecture. Grab a Cuban sandwich in Little Havana, then ride the vintage carousel at Virginia Key Beach Park.
