Nothing screams good times like a road trip, particularly when you’re headed someplace as wonderful as Boston. With big-name sights like Fenway Park and TD Garden, there’s so much to see in so little time. That’s where a rental car can be a blessing. You’ll be able to check out loads more places — but choose something small for easy city driving, like a compact car. If you don’t want to cruise around those daunting streets, Massachusetts abounds with natural wonders. Ditch the zippy car for something larger, like a standard vehicle, and explore the most popular bays.
