You will likely get some advice from Michael "Ask me about golf in Maine" Moore, but I can take a crack at it....
Assuming you will be playing Cape Arundel....
The Ledges in York, ME...Brad Booth
Portsmouth CC in Greenland, NH...50s RTJ on a great tidal inlet site
The Oaks in Somersworth, NH is a new one that looks pretty good...I think Brad Booth also. It's one of his "featured projects" on his website.
Cape Neddick is 9 Ross, 9 Cornish?
Biddeford-Saco is the same as above...
Nonesuch River has gotten ok reviews I believe
Sanford CC is supposedly ok but difficult and very tree-lined.
Links at Outlook is ehh, but some like it...
The privates would be Manchester CC, York GC (might be worth a begging call), and Portland CC.
Some of these are in between Manchester and Kennebunk on the back roads, although the Ledges is decently close to 95, and Portsmouth CC is too. Nonesuch River, Biddeford, and Portland are north of Kennebunk...
