"Don’t skimp on the rental car. It’s hard to feel good about yourself while driving an econo-box. Luxury rentals don't cost much more than the standard-size cars and their comfort means you’ll arrive without a stiff back. In Las Vegas, you can even rent an exotic for the day. Trading the Taurus for a Lamborghini Gallardo or Ferrari 458 Italia is a great feeling, if only for a day."
