There are places set aside for kids at nearly every resort property on the Strip. Whether it’s a nook filled with video games, a more elaborate arcade complex at the entrance or exit of a show or attraction, or the attraction itself (virtual reality, roller coaster, gaming arena), they are amenities that parents toting toddlers around at 10 p.m. pick up on quickly. Ask any kid more than 4 feet tall with insider information on Las Vegas where the action is, though, and they can answer in one word: Adventuredome.

Circus Circus, which observed its 50th anniversary in October, contains the Strip’s only dedicated indoor amusement park. Its translucent big top covers 5 acres of radical rides, midway games, bumper cars, laser tagging and roller-skating that can occupy children’s attention spans for a half-day or more. It’s more likely adults will wear out first, but there is ample space set aside for observation areas once parents and guardians have had enough of defying gravity.

Kids with limitless energy and a day pass will probably spend most of their time on the mountain that rises up within the big top and provides height for the two coaster rides that wind through, over and around it. The Canyon Blaster does what its name implies and more, speeding up to 55 miles per hour on a pink track that double-loops and double-corkscrews. While the Canyon Blaster is more of a traditional roller coaster experience, El Loco’s twists, turns and drops are more state-of-the-art. Riders ascend 90 feet before feeling the g-force of a sharp drop, experiencing a 240-degree barrel roll and tipping 90 degrees during a straightaway.

The Inverter is less complicated but more dedicated to demonstrating the feeling of g-force. A 20-seat cart spins on a giant arm that rotates clockwise like a stopwatch going backwards. The cart then spins clockwise, causing riders to essentially rotate in both directions at the same time, and at one point stopping upside down at its highest point. The Sling Shot is another apparatus designed with g-force in mind, shooting passengers straight up a tower that reaches the top of the big top before a short free fall provides head rushes for all.

For a spin on spinning rides try the Disko, which places a whirling circular platform on a U-shaped track that causes the ride to swing and spin at the same time. Chaos promises a different experience each time due to the three ranges of motion on the “ultra-thrill ride,” while more sedate experiences await children of all ages on a classic carousel and Ferris wheel with cars designed to look like hot air balloons.

There’s much more beneath the big top, including 4-D theaters that feature SpongeBob SquarePants and characters from Ice Age, and extreme ride theater features starring dinosaurs and Angry Birds. On Friday and Saturday nights the lights are dimmed for the glow of neon rides, face-painting and roller skating, but the fun never stops when Adventuredome is open. Ask any Vegas kid.
