Get ready to be busy, because there’s a huge amount of things to stick on your to-do list. For instance, National Aquarium in Baltimore and M&T Bank Stadium. Oriole Park at Camden Yards, Baltimore Museum of Art and Fort McHenry are other wonderful attractions. And don’t forget about Washington Monument! Cramming all the major sights into your Maryland vacation will be a lot easier with a car rental. You can add some wheels to your Expedia booking after you’ve locked in your cabin.
