Grab your bags, exit the arrivals hall at Chicago, IL Airport (ORD-O’Hare Intl.), and pick up your rental car. Which one you jump into depends on where you’ll be going. If you’ll be spending the majority of the time driving in downtown Chicago, around 16 miles from the terminal, opt for something small and zippy. A compact car that’s fuel-efficient will be perfect for those busy city streets. But with a smorgasbord of things to see, like the striking prairies of the surrounding area, you’ll probably be racking up a few miles. A larger vehicle, like an SUV or a full-size car, will make longer road trips a joy.
