First time emerald cruisers an overall great experience. Have been on Viking for the Portugal through the Douro Valley. Food, cabin, staff and overall boat accommodations on par with Viking. Emerald could do better in the cultural experience we found the evening entertainment lacking just a bit. Although our activities director was fantastic but too many game nights. A German cooking class, or other cultural activities of the region would be an improvement. Since we are from the states we want to soak up as much as possible. If you plan the port ahead to find the hidden charms these beautiful cities has to offer you will enjoy it even more. Our age group is late 50’s the active selections for tours was a plus that was not offered by Viking. Active selections include biking through the valley and hiking through a vineyard to the top of the mountain for a beautiful view and a talk about the vineyard, valley and monument. River cruising is the way to go.
