Grab your luggage, exit arrivals at Phoenix, AZ Airport (PHX-Sky Harbor Intl.), and pick up your rental car. Which one you climb into depends on where you’ll be going. If you’ll be spending the majority of the time driving in downtown Phoenix, around 4 miles from the terminal, consider something zippy. A compact car that’s fuel-efficient will be perfect for those bustling city streets. But with almost endless things to see, like the striking canyons of the region, there’s a good chance you’ll rack up those miles. A bigger vehicle, like an SUV or a full-size car, will make lengthier road trips more comfortable.
