This was a wonderful small-boat cruise on the Duoro river. We thoroughly enjoyed it. We were expecting some walking tours of the ports where we docked each day, but were almost always met by Viking buses that took us to other interesting sites in Portugal. It was a combination riverboat and bus tour. The buses were nice, but it seemed we spent a lot of time on them.
One of the highlights was the Sandeman winery. We were re-introduced to Port wine, and have continued to indulge after our return home. Viking is very generous with the local wines at every lunch and dinner in the dining room.
The Viking Torgil is a baby longboat with less than 100 passengers, so we got to meet all of the crew and most of the other passengers during our time on the boat. I was fascinated at how well organized was our passage through the Duoro river locks - five going upstream, and five returning downstream.
The suite was very nice, and not much more expensive than a standard cabin. The weather precluded much use of the balcony.
