There were six in our party and this cruise was an unanimous choice by all of us. The crew could not have been nicer, the food was wonderful and our cabin was very comfortable. The weather did not cooperate as it rained every day but one. My favorite city was Strausburg ( we had sun that day) but the city is beautiful. We also enjoyed seeing the windmills and the scenery along the river. We would not hesitate going on another Viking cruise. One of the couples with us celebrated their 40th anniversary on the cruise and the ship gave them a bottle of champagne to share for the celebration. The one thing that impressed me was how clean the ship was and how the crew went out of their way to help make the cruise wonderful. We will have a hard time deciding which cruise to go on next.
