Maine is almost an iron butt each way. If you are trying to do something in less than a week I would suggest Vermont and New Hampshire. Closer and way better roads. Maine is kinda bla when it comes to fun roads. Great scenery and food but roads not so much.
Yes I love to have you stay ! I really don’t rent it out till after memorial day because because it’s on the river and river is dangerous in off-season to boat in sometimes so I pull the boat dock from end of April to November
