Even though we travelled extensively in Greece in the mid-1980's we found numerous excursions that took us to new territory. We thoroughly enjoyed this itinerary and we bought a number of additional excursions.
Pros
1) We were happy with all stops and excursions except the included tour of Marseilles France (we made the best of it by walking briskly around the old port, which, has since our last visit, has been made into a public pedestrian walk).
The chairs in our deluxe veranda state room were marginally comfortable. When you are on board for 3 weeks you need to assume that some evenings are "stay in". Also, seems you have to beg for additional hangers. This should be an item you could order through the "Viking Journey" on their website.
