The route we selected was the traditional Rhine river cruise with an excellent itinerary.
We selected Scenic based on the innovative cabin design with the balcony that could be either separated from or made part of the cabin by means of folding glass doors. The balcony could also be protected from the elements if necessary by means of a glass panel that could slide up from the lower section and create a glass wall.
Scenic advertises that it is all inclusive and it really is. All drinks of all types were included at all times of day and night.(there were a few exceptions such as Dom but we were very happy with all the available high quality wines, liquors and beers)
The room was beautiful with adequate closet space, very comfortable bed , large walk in shower in the bathroom. Felt spacious . enjoyed the balcony setup described above. Good location midships, no engine noise. Compromise on cost on middle level ( not top floor)- never heard noise from above.
