Grab your suitcase, walk out of arrivals at Baltimore, MD Airport (BWI-Baltimore Washington Intl. Thurgood Marshall), and pick up your rental car. Which one you slide into depends on where you’ll be going. If you’ll be spending a lot of time driving in downtown Baltimore, around 8 miles from the terminal, select something zippy and small. A compact car with good handling will be ideal for navigating those bustling city streets. But with a wealth of things to see, like the scenic dunes of the surrounding area, you may want to add some pit stops. A larger vehicle, like an SUV or a full-size car, will make longer road trips a joy.
