Want a break from the blackjack tables or pools? Head over to Pole Position Raceway Kart racing track. These racing go-karts are awesome. They are pretty quick and tons of fun. They supply all the safety gear and all of your lap times are posted on a screen and you get a printout after you are done showing how you stacked up against your friends and the others who have raced there that month. It is a little on the pricey side but this is Vegas and what worth doing is not expensive? My friends and I are actually going to rent out the entire track for ourselves for an hour or two next time, with a big enough group it actually saves you money and you will get more track time.
My only slight complaint is that all the cars are not equally matched performance wise. One time I had a super fast kart and the next race I got lapped by everyone, a more level playing field would make for more fun, especially with my group of ultra competitive friends.
