Wanted to try a river cruise. Chose Viking because it had a 2 for 1, and special on airline tickets . Also, excursions were included. It is called the elegance of the Elbe river. Started in Berlin and ended in Prague. The ship requires at least 14 inches of water ; the Elbe is suppose to be one of the shallowest rivers in Germany, so Viking designed a ship specifically for this river. We did get an email that it couldn't go to a couple of destinations and would require a motor coach to reach the sites. We went down as far as it could, did a u tiun to go back to Dresden (not a bad place to end up in) loved the experience. It is the smallest, and there were about 96 people on the cruise. Met some fascinating people on the cruise. Excursions and guides were great. Staff ratio is 1 staff to 3 guests.
