This Google review was posted by "Caleb" today.

"Super friendly. People at almost every stop. Very helpful in making sure we were getting on the right bus and getting to where we wanted. They went out of their way to ask if we wanted help. I had no idea this service was a thing. But so glad we had. We took it out of Bar Harbor from Village Green meaning we never had to move our car or worry about parking the entire time at Acadia. And good thing too because there was no parking anywhere left. I'm surprised not more people utilize this free service. Lots of busses. On time. So never much wait. And they always had room."
