If ya want
offbeat and a little
cheesey, you could take her to the "Desert of Maine." It is off exit 19 or 20 (cant remember) on I-95. Its a bit different and so are the people.
When I was in my wee-early 20's, some friends and I took a RoadTrip through the NewEngland states and for whatever reason or substance (hehe)- this place sticks out most in my mind.
EDIT: Arent most Tourist attractions/traps cheese?
If that doesnt do it- I also seem to remember that off to the east (south east) is a REALLY BIG BIG body of water.
Just some thoughts.
EDIT2: Seriously, What area ya going? Tourist Southeast Part on Coast (Perils of 95)- anywhere starting at YorkHarbor/York up through Portland is active and offers Much! To get out of the way and off the Beat head up toward the Border around the Allagash Wilderness area- Lots of cool small towns and people. I have never been to the Western parts of Maine.
