We decided to take our first river cruise with Scenic based on the recommendation of our travel agent who said it was the best and most modern line on the Rhine/Danube.
The Scenic Ruby and all the Scenic ships in Europe, I believe, all have balcony cabins on the second and third decks with a few non-balcony on the 1st deck. I was extremely pleased with a few minor exceptions about this trip.
The ship is very attractive in and out and really shines in contrast to the other ships we saw on the Rhine and Danube. The staff is superb, friendly and attentive. The group is somewhat older which I'm told is the norm on river cruises.
I was in 217 on the Scenic Ruby. It was a comfortable cabin about a third of the way back of all cabins.
The back cabins have more vibration.
