I rented a car at Boston Airport. After getting off the plane, you can take shuttle bus 33 or 55 for two stops to reach the car rental center. Very convenient. The Hertz signage is big and noticeable, and the staff was very friendly. There was no line, and the process was quick. They initially offered me additional insurance, but after I told them I already purchased full insurance from QEEQ, they didn't insist.
