My wife and I did this cruise because we wanted to experience a different type of cruise experience. We usually cruise on sailing ships (e.g. Windjammer Barefoot Cruises, Star Clippers, Windstar) and we generally like smaller ships. We were worried about the water levels and if we would have to change ships midway - fortunately, we were able to stay on the ship through the whole cruise.
The ship itself is beautiful, with great rooms. We enjoyed having a balcony where we can watch the swans when at port and also the locks when changing to different parts ofthe Rhine.
The food was excellent, as were the wine choices. We generally stuck to the house wines and id not get a drink package, because we are not big drinkers.
