Many friends started talking about their good experiences with river cruising, many with Viking. After looking thru Viking's catalogue, I convinced my husband to go from Prague to Paris (Cities of Light). On a river cruise, you do not have to pack and unpack. While we were in a new port every day, starting in Wurzburg, Germany,we never felt rushed. Most of our outings were by foot, rather than daily bus rides. The cabin was comfortable and Viking makes use of every inch. Meals were always good and being able to pick you meal partners was great. Small ships are perfect, as you get to know almost everyone.
My husband really enjoyed the river cruise part of the trip. He is perhaps typical of some others, after seeing 1 castle and 1 cathedral, he has seen them all. I, on the other hand, was fascinated with all of the beautiful and historic buildings.
I would recommend this type of travel with Viking to anyone wanting to see other cultures. The Cities of Light cruise travels on 4 rivers. The itineray goes both directions, Prague to Paris or vice versa. Give it a try!
