Are you kiddn' me? Nobody mentioned going to Shelby. It's awesome! They give tours of the shop at 10am, I believe. GREAT SHOWROOM! I won't spoil it by telling you what he'll see. Trust me, it's worth the $30 cab ride (one way). It's out next to the speedway.
Are any of them into NASCAR. If so they should get a bite to eat at the NASCAR cafe located in the Sahara Hotel located on the strip. Its tourist priced but the foods not too bad. The roller coaster is a blast.
