Yes, Exotics Racing. On Las Vegas Blvd just south of town. You'll need an Uber. Try and book it on the morning so it isn't so hot. The AC is off when you run.
Picking a car can be hard. My suggestion is if they have a car you always wanted to drive pick it. They are all fast as hell. The Hurican is more forgiving, it's computers will help more when you mess up. The Porsche GT2 is the fastest they have....when I went there but it is harder to drive.
Go see a show. It's a blast. Copperfield, or a music act that you want to see.
You can rent fully auto guns at a range. You can rent construction equipment and dig holes or smash cars.
Pawn Stars was underwhelming.
Downtown Old Vegas is a must see, at night.
Each hotel has some kind of attraction. Look at them all and go to ones you like. Mob museum. Lady Gaga museum...all kinds of stuff.
Also the pinball museum is worth a few hours of you like to play pinball. They have them all to play.
