GoalStopper - I'm also from SoCal and I always go by plane. Last time I drove to Vegas (over 20 years ago), I knew it would be my final road trip to Sin City. I jump on Southwest out of Ontario and land in 45-50 minutes. Can't beat that! A very easy and quick flight and if I book ahead, airfares can be very reasonable. Once you fly, you will never drive again.
