A city trapped in time, Havana captures the imagination like no other. Faded glamour meets careful colonial-era reconstruction with a backdrop of irresistible colour. Walk El Malecón, the walkway bordering the ocean; visit Old Havana and the Catedral de San Cristóbal; and listen for salsa music, open-air bazaars and parties that last all night.

Atlanta has been dubbed everything from the "capital of the new South" and "the next international city" to "the best place to do business." It's also a great place to visit. Fueled by the prosperity of local mega companies like Coca Cola and Holiday Inn, the prestige of hosting the 1996 Summer Olympic Games and the energy of young upwardly mobile types who have migrated to the city in droves - Atlanta is on fire. And this time it's a good thing. From world-class restaurants and a myriad of cultural attractions to a hip nightlife and sporting events galore, the city is cosmopolitan in every sense of the word. But Atlanta has also managed to maintain its historic character. Stop by the Atlanta History Centre or visit the Martin Luther King Jr. Historical Site, a moving tribute to an American icon. Browse through the former home of famous author Margaret Mitchell or pop into the Jimmy Carter Library and Museum for details on the life and times of the former president and his family. Whether you choose modern urban endeavors or old southern pleasures, Atlanta will not disappoint.

Live music is the essence of Austin, but it isn’t even close to the whole story. With spectacular entertainment districts, ubiquitous culture and top-notch restaurants, Austin allows you to create your own soundtrack. Austin boasts more than 250 music venues, the world’s first James Beard Award-winning barbeque pitmaster, an eclectic arts scene and the unique migration of 1.5 million Mexican free-tailed bats. Take a look around and put the Live Music Capital of the World on your playlist.

It's called the Live Music Show Capital of the World-- on any given day, almost 90 music, magic and comedy shows run at 50+ theatres. You might catch into Tony Orlando, the Osmonds or Marty Stuart, all regulars. (Think Las Vegas without the casinos and people drinking margaritas-by-the-yard at 10 am.) Between shows, enjoy nature in the Ozarks-- you'll find great fishing, hiking, biking and water sports in the area.

From the National Mall’s monuments and memorials to vibrant neighbourhoods filled with character and charm, DC is a world-class destination featuring breathtaking views, award-winning hotels and hundreds of free things to do.

Located on the shores of Lake Michigan, Milwaukee is perhaps best known for its famous breweries and the Major League Brewers, but there's more to the city than beer and baseball. Milwaukee is rich in historical and cultural attractions, making it the perfect place for a weekend of exploring. Visit the newly expanded Milwaukee Art Museum or the Mitchell Park Horticultural Society, which hosts an annual show of the same flora and fauna seen in Georgia O'Keefe's paintings. Those interested in the city's history can visit the grand Pabst Mansion, former home of one of the city's famous beer barons, or the Milwaukee Public Museum, to see what life was like in Old Milwaukee. If you have children with you, don't miss the Milwaukee County Zoo or the Betty Brinn Children's Museum. Of course, a trip to the "Genuine American City" would not be complete without a tour of the Miller Brewing Company and a Brewers game at Miller Park.

Home to two of America's most prestigious universities, Cambridge exudes a certain intellectual quirkiness. A mix of historical haunts, student hang-outs, alternative art and culture venues, vintage clothing shops, bookstores and ethnic restaurants, the city is, well, really cool. Although it is located just across the Charles River from Boston, Cambridge has a distinct vibe that is noticeable immediately. Start at Harvard Square, a hub of activity and mishmash of trendy stores, outdoor cafes and colorful local characters. Pick up a walking tour map at the visitors information booth in the centre of the Square. The route will take you past many important landmarks including the Mount Auburn Cemetery, Tory Row and the Longfellow National Historic Site. Harvard University offers student-led tours through the illustrious buildings and monuments of its sprawling campus. Art and architecture buffs should meander around the M.I.T campus, which includes outdoor sculptures by masters such as Picasso and 20th-century buildings designed by modern greats like Eero Saarinen and I. M. Pei. Along the way, browse through bookstores, stop to watch street performers and grab a coffee at an outdoor café to take in all this captivating city has to offer.

Is there any possible way Las Vegas could not be on our "best nightlife" list? The only way we could possibly omit it is on a technicality—since you can do pretty much anything 24/7 in Vegas, it might be wrong to call it "nightlife."
