My husband and I have been on 2 Viking River Cruises, both of which we enjoyed. The first was on the Danube and the second, the Rhine. We both loved the Danube experience and would certainly recommend it to all potential travellers. The Rhine cruise however was taken too early in the year (the first week of the season) and we had to contend with cold, wet and windy weather at the start of the cruise - which wasn't the fault of Viking!! Unfortunately, my husband caught a virus at the start of the cruise which put a 'damper' on participating in all the events provided for the passengers. However, we have no complaints on either the staff/crew, the boat or quality of the food provided. Our next trip though will certainly be taken later in the year!
