If we're gonna talk party cities, we have to start with the original Sin City. Known to the masses as the ultimate adult playground, leave your inhibitions behind at some of the world's hottest clubs and casinos. Indulge your vices on The Strip, party poolside with bikini-clad models, rally around the clock with the world's leading DJs, and gamble your savings away - just to win it all back (we hope). After all, what happens in Vegas…

If there's one place in the world that's synonymous with party - it's Ibiza. A dance mecca since the '80s, this Mediterranean island off the coast of Spain has hedonism flowing through it's veins. Drawing thousands of revelers during the Summer months (which last from May through October), Ibiza's incomparable DJ lineups, spectacular beaches, and non-stop ragers keep even the most jaded of partiers coming back for more.

Holland's notorious capital makes the list for its unique partying style. Between space cakes and live sex shows, Amsterdam is a beast all its own. Beckoning thousands of tourists each year to break taboos with their eclectic cannabis coffee shops, unapologetic Red Light District, vivacious after-hours parties, and festivals (including the noteworthy Cannabis Cup) - this is the place to do all the stuff your country says that you can't.

Home to techno music and the annual Love Parade, this capital city attracts millions every year. Ditching the posh vibe of fellow party cities, Berlin throws the emphasis on a hipper crowd that keeps the city buzzing with top notch music venues and underground clubs that stay open all night long. To really mix it up be sure to check out the now infamous mega-club Berghain, which roots itself in "sexual open-mindedness," day-long parties, and a rich history as the focal point of techno-subculture.

The laid-back Quebec capital may be known for its penchant for French language, jazz clubs, and distinctly Bohemian vibe - but beyond the Old City is a nightlife busting at the seams. Overrun with a dense student population, packed discos, late-night bars, and an endless slew of festivals with a heavy emphasis on electronica (Piknic, Igloofest, MUTEK, etc), this city stays hot - even when it's 30 below.

One can't talk about Thailand without mentioning the Full Moon Parties on Koh Phangan Island. Held once a month under the full moon (unless it falls on a Buddhist holiday), tens of thousands of ravers descend into debauchery on Haad Rin Beach. DJs whip the crowd into a frenzy with everything from trance to D&B to reggae, while drinks are served up by the bucket.

With no lack of perfect sunny weather and brag-worthy beaches, Miami is a party zone all its own. More than just a Spring Break destination, South Beach rages all year round with celebrities and eye candy always out in abundance. Soak in the tropical sun on white beaches, dress to impress, and save your energy for the packed mega-clubs that last all night long. If festivals are your flavor, be sure not to miss the annual Ultra Music Festival and Winter Music Conference, which pull in the hottest DJs from around the world.

If you're looking for a Winter escape, book a flight for the beaches of west India. Entering the party scene in the '60s when Western hippies began to reach the city's beaches, their lasting bohemian influence can be heard through the psy-trance and techno beats that penetrate the beaches. Throwing down underground bashes along Anjuna Beach and kicking things up for outrageous annual Christmas and NYE parties, Goa has gained recognition as an ultimate party paradise.

Now known for its beautiful women, affordable prices and sensational dance scene - Budapest has come a long way since the end of the Communist regime in 1989. Quickly climbing the ranks with all-night clubs, luxury hotels, and casinos dotting the Danube River, Hungary's largest city has gained international recognition. Hosting the Sziget Festival and visited by the world's largest traveling club, Sensation White, Budapest has rapidly become one of the top party cities in the world.
