If you are going to Acadia then I would suggest Smugglers Den in Southwest Harbor. Be sure to stop at Rats for your local seafood. I know it doesn't sound like much, but you will be pleasantly surprised.
When in the N Conway NH area, I would suggest Glen Ellis CG in Glen NH. It is on the other end of the N Conway strip and closer to Mt Washington. You can tube the Saco river right from the campground. The river runs right by it.
I have not been impressed with VT CG's. Still haven't found any I really like. You would have better luck in W Massachusetts (Berkshires area). Pine Acres (Oakham, MA) is directly north of rt 84 (Sturbridge, MA) and is a very nice CG.
