Boston to Nova Scotia and back, 7 days, what not to miss

We have friends who almost routinely will drive to Boston area to see football, hockey or baseball. There, the Boston teams are number one, and they do these drives in one day. In our motor home, and with no time restraints, we stopped overnight at Bangor. But driving through to Cape Breton in a day is stretching it, to Fortress Louisburg. But it could be included in your five-day schedule.
