That depends largely on where you’ll be wandering. Downtown Newark, about 12 miles from Morristown, NJ Airport (MMU-Morristown Municipal), can be a little daunting to drive around. Make things easy for yourself by booking something small, fuel-efficient, and a cinch to handle. Keep in mind that Newark is also the gateway to some of the sandy shores in New Jersey. If your escape is more about cruising down long stretches of road, then you may prefer something with a little more trunk space and room to move about. How about a full-size car or a standard SUV?
