Scenic are by far the most friendly and professional of the river cruising companies. Excellent service with an outstanding menu and so many shore excursions to choose from.Staff were always friendly, courteous and always available to provide additional information. Cruise director Tadej was outstanding He handled the change of ships with ease and it was of minimal inconvenience to the passengers. Shower was a little small in the Crystal. Adequate room in the State room for a couple, but may be a bit tight for 2 singles. Ports were great with interesting and variety of shore excursions, would have liked to spend longer at some ports. Able t change excursions with no fuss from the Crew. Dining was exceptional with many courses for each meal and all drinks included. The gym was adequate if you wanted to work out. The sun deck was a great vantage point for the senasational river views along the way. A great cruise for an overview of where you would like to go back to and spend more time.
