We were treated royally onboard and had comforts galore, down to the heated bathroom floor. The food was excellent and we enjoyed trying the regional favorites each day. The castles along the middle Rhein were breathtaking, and cruising was relaxing. We could have done without all the alcohol and liquor though. Our bike ride in Kinderdijk, and going into a working windmill, was a highlight. Hiking in the Black Forest was our favorite moment, but we only had 45 minutes. We would have like 3-4 hours there. There were other cities we wished we could have visited, like Bacharach and Bonn.
