Hi,

My trip was a few years ago, so I am not sure this is the most relevant. I am sure others will chime in.

You could drive up to New Brunswick from Portland, or you could take the CAT from Portland or Bar Harbor (next to Acadia) into Nova Scotia, and then drive.

We drove through NB - we stayed in Fredericton and St. John, but only for a day each. There are a few things to see, but I would not say 1 week. Definitely Bay of Fundy - that was awesome. Also loved the reversing falls and the river surge (forget what it was called). Of the two, I liked St. John better, its smaller and prettier.

A drive to PEI is definitely doable, and totally recommended. I would say that PEI has the better beaches, plus awesome seafood, and really friendly people. The bridge to PEI was also interesting (toll road, and no pull outs).

A word of warning - if you are planning to return on a Sunday down Interstate 95, beware of the traffic - a LOT of people who are not in any particular hurry, most towing boats or RVs. Speeds on the interstate average about 30-40 miles/hr - if you are lucky. I love that area - but I always plan to come back a day late or early just to avoid the horrible traffic on Sundays in the summer!

Have a great trip!
