I admit it takes a little longer, but since most of the tourists head for MDI, no problem, only adds two hours to the drive.
I strongly encourage everyone to stay on the pike. Do not get off at South Portland. Do not go up 95. Do not get onto route 1, thereby getting in my way when I'm trying to make a ferry...
I remember that. The turnpike is faster. I have known of people taking a motel but have to take the turnpike a couple times a day to get to the beach.
