We are on this cruise exactly one year from now. We are in our early 70's and have visited large cities and famous museums and decided on a cruise with focus on wonderful scenery this time. You have confirmed through your blog and gorgeous photos that it is the absolutely the best choice. You frequently mentioned the "panoramic" included tours. Wondering if you joined any of Viking's optional excursions. If so, what did you think of them? Thanks again for all your postings!
