Finally, after all our yammering about how Vegas isn't for families and how most of the remaining options are really overpriced tourist traps, we can whole-heartedly recommend an actual family-appropriate entertainment option. Part arcade, part go-kart racetrack, this is exactly what you want to help your kids (and maybe yourselves) work their ya-ya's out. The arcade is well stocked, with a better quality of prizes than one often finds, but we suggest not spending too much time in there, and instead hustling 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 road track in Vegas, full of twists and turns as you try to out-race other drivers (be a sport, let the little kids win occasionally), to a high-banked oval built just so you can try to make other drivers take spills on to the grass, to, best of all, a timed course. The latter requires a driver's license, so it's for you rather than your kids (but the wee ones will find the 4th course is just for them), and here you can live out your Le Mans or Police Chase fantasies, as you blast through twisting runs, one kart at a time, trying to beat your personal best. A good kind of adrenaline rush, believe us. 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 main Strip action -- here's where you'll need that rental car, for sure. Note: Kids have to be at least 36 inches tall to ride any of the attractions.
