Finally, after all our yammering about how Vegas isn't for families and how most of the kid-friendly options are really overprice tourist traps, we can wholeheartedly recommend an actual family-appropriate entertainment option. Part arcade, part go-kart racetrack, this is exactly what you want to help your kids work their ya-yas out. The arcade is well stocked, with decent quality prizes, but don't spend too much time in there and instead hustle outside to the slide, the little roller coaster, and best of all, the four go-kart tracks. Each offers a different thrill, from the longest track in Vegas, full of twists and turns as you try to outrace other drivers, to a high-banked oval built just so you can try to make other drivers take spills onto the grass, to, best of all, a timed course. The last requires a driver's license, so it's for you rather than your kids, and here you can live out your police-chase fantasies as you blast through twisting runs one kart at a time. The staff is utterly friendly, and the pizzas at the food court are triple the size and half the price of those found in your hotel. The one drawback: It's far away from the main Strip action, so you'll need a rental car. Note: Kids have to be at least 36 inches tall to ride any of the attractions.
