The cruise ship and the staff on board are top notch. Previously did scenic and say the ship and staff are comparable.
As a bonus, the ship was only half full and we had a great time.
Note that the itinerary is less impressive than others as there are fewer choices in each port. The food was better than I expected and good - and a good selection of wine for each meal was provided. The localization of the menu to each destination was not as good as I would have liked (based on other river cruises).
