Euro,
I always go to the In-n-out on I-15 and Flamigo Blvd, south strip, cant miss it with the big neon sign and right off the exit, always busy, there are others but I don't know if they are easy to get to....The Cannery may be one of the closest motels to the speedway, and is a easy drive. . Kids should be ok, the show and cars are outside, so there is some room to mess around.
