Las Vegas may be a playground for adults but there is one place that's all about the kids.Head toward the north end of the Strip and you really can't miss the giant neon clown sign and massive pink and white circus tent-shaped building that is Circus Circus, a classic Las Vegas hotel since 1968.The hotel is so iconic you've seen it in movies like "Diamonds Are Forever" and "Austin Powers: International Man of Mystery." It was also mentioned in Hunter S. Thompson's famous book, "Fear and Loathing in Las Vegas." In fact, we think he described it perfectly: "The place is about four stories high, in the style of a circus tent, and all manner of strange county fair/Polish carnival madness is going on up in this space." That madness is exactly what makes Circus Circus such a great place for families. The accommodations are affordable and you'll find an absolutely endless supply of entertainment for people of all ages.True to its theme, the hotel boasts the world's largest permanent circus under a big top inside. Just follow the sounds of guests oohing and aahing and you'll find acts like aerialists, jugglers, acrobats and trapeze artists flying through the air with the greatest of ease. The best part? The performances are totally free.Sharpen your ring tossing skills and head to the midway, which offers more than 200 classic carnival games. Didn't win at the tables? You can at least win yourself a giant stuffed animal here. There's also an arcade with classic and current video games.Go back to your room and take a quick power nap because, even though it doesn't seem possible, the fun doesn't stop there. The biggest attraction at Circus Circus is The Adventuredome, America's largest indoor theme park. It doesn’t matter if it's the hottest summer day or a chilly winter afternoon, the dome is a comfortable 72 degrees and ready for action year-round.The five-acre park has a dizzying (literally) array of rides to choose from. The brave at heart can hop on the Canyon Blaster, a double-loop, double-corkscrew roller coaster. The younger set will enjoy Miner Mike, a runaway coal train, or the Thunderbirds, a squadron of not-so-high-flying 1920s-style airplanes. The Adventuredome's newest thrill is the El Loco roller coaster. If you're loco enough to ride it, you'll experience a 90-foot ascent, negative G drops, gravity-defying turns and over-the-edge twists.Parents might need a bit of adult time after all that sensory overload and luckily Circus Circus has plenty for the 21 and older crowd too. The resort has a full casino, a race and sports book and there's the adjacent Slots A Fun casino where you can play the slots, shoot some darts or watch sports on big screen TVs.Adults will also appreciate the hotel's gourmet dining room, THE Steak House, which has earned acclaim in Las Vegas for more than 30 years for its perfectly prepared prime cuts of meat and old school service. If you're still standing at the end of a fun-filled day with the kids at Circus Circus, you deserve a shot, so head to rock 'n' roll legend Vince Neil's Tatuado Eat-Drink-Party! and Party Bus Bar, which features flair bartenders and party girls offering up creative cocktails.
