If you're looking for a place to stay in Las Vegas that will put you close to all the party action, head to the Hard Rock Hotel & Casino. The resort boasts a 24-hour rockin' atmosphere that appeals to the young, hip and trendy.Located a few blocks east of the Strip, which isn't far but can be a challenging walk (especially if you've had a few too many drinks), the hotel oozes rollicking good times -- from its peerless concert venue and pool complex to its sleek nightclub, swanky restaurants and super sexy retail offerings.Built in 1995, the "old" Hard Rock Hotel & Casino is as happening as ever. And, as a result of an expansion project that concluded in 2010, the property has added a couple of new room towers -- the luxurious Paradise Tower and the all-suite HRH Tower -- as well as several pools and leisure amenities.Of course, live music reigns supreme at the Hard Rock Hotel & Casino, and The Joint has an incomparable reputation. What other stage has been graced by Bon Jovi, Paul McCartney, Incubus, Linkin Park and The Killers, just to name a few? Following a redesign, this state-of-the-art facility now has seating for 4,000 people along with sound, projection and lighting systems that are so advanced they defy easy description. Simply put, there's no better place in town to see and hear your favorite performers.The resort recently debuted a more intimate live entertainment venue -- Vinyl. It features a diversity of genres along with local bands, comedy and late-night burlesque. The main nightclub at the Hard Rock Hotel & Casino is Body English. It's a sensual place -- filled with leather furnishings and giant chandeliers -- that showcases indie, electronic, rock and pop music. The resort also has Vanity (it's only open for special events and parties), with a decadent interior that includes hand-cut crystals, antique mirrors, chrome accents and rich tapestries. Those who want to forego the nightclub scene will still find a party vibe in every other nook and cranny of the property. Two circular bars crammed with people are the beloved Center Bar in the original Casino Tower and the newer Luxe Bar in the HRH Tower. Sports fans can enjoy watching the day's action on countless big-screen TVs spread throught The Ainsworth -- an elegant new nightlife-oriented venue from New York City that serves stellar cocktails and a small menu of upscale American bar food.During the summer months, guests can revel by day at Rehab (held at the Paradise Beach area). The Hard Rock Hotel & Casino originated the now widespread "pool party" in Las Vegas. In fact, the weekly Sunday event has become legendary. Imagine a throng of bodies in the skimpiest of swimwear sunbathing, drinking and dancing to music spun by DJs in a stunning complex that consists of expansive freeform pools, a waterfall, sandy beach areas and kitted-out cabanas. Blackjack and other games are available at swim-up tables. For a more low-key experience in an equally lush landscape, go to Nirvana Pool, Breathe Pool or the pool sanctuary at the Reliquary Spa, which also features a menu of treatments from around the world.The dining is as self-indulgent as all other aspects of the Hard Rock Hotel & Casino. Nobu is home to modern Japanese cuisine and Fú offers a unique fusion of Asian fare, while 35 Steaks + Martini mixes a classic steakhouse ambiance with sensual signature cocktails. For casual eats, there's Pink Taco and everyone's favorite -- locals and visitors alike -- Mr. Lucky's Café, which recently got a modern update in décor and food offerings. But you can still ask about the $7.77 special (a six-ounce steak, three shrimp and mashed potatoes), which isn't listed on the menu, at this laid-back 24-hour coffee shop. Restaurateur Sam Fox opened Culinary Dropout, a swanky drinking and pub grub-style dining spot, adjacent to the pool. Indulge in everything from fried chicken and biscuits to the signature After School Special cocktail here.In addition, the retail therapy at the resort is distinctive. All of the stores are targeted to youthful trendsetters. Visit Love Jones for lingerie and Rocks The Jeweler for some urban bling as well as John Varvatos for men's wear and the Hard Rock Store for logo gear. The Hart & Huntington Tattoo Co. even opened a locale for guests who get the urge for a new tatt.Last but not least, the Hard Rock Hotel & Casino has an extraordinary collection of rock 'n' roll memorabilia in frames and shadowboxes that line the walls and hallways throughout the premises. It's like going to the coolest music museum in the world and not having to pay a dime. With every corner turned, your eyes will behold things like a guitar from Coldplay, a drum kit used by Aerosmith and the clothes worn by Fergie, Britney Spears and Christina Aguilera in their music videos.When you come right down to it, Las Vegas is Sin City, and by staying at the Hard Rock Hotel & Casino the opportunities for sinfulness run rampant.-- By Renée LiButtiNote: In order to maintain a safe environment, Hard Rock Hotel & Casino prohibits coolers, boxes, bags or other containers for the purpose of transporting food and beverage on property.
