Masaki posted a very detailed review of this cruise in 2004. He did the 7 day version. Here is a link to his reviews which were pretty right on:

I posted a review that I can't find in the review section. We did the 9 day version - it was a wonderful cruise. The best lobster we had was in Dalvey, PEI. We also had lobster on the Excursion in Bar Harbor, Lunch, Cadillac Mountain and Acadia. That excursion was quite nice. We enjoyed hte Peggy's Cove excursion since we are into photography; And there was not enough time in Quebec. We did the walking tour and high tea there.
We did our post cruise at the Ritz Carlton which was in a perfect location - close to everything. Amex Platnium had a special of $159 per night for a great room and included a high tea and breakfast.
Which itinerary are you considering?
