We departed September 21, 2013 on the 14th cruise for this new ship. For a river cruise boat this is the best I have experienced. The ships are well designed and the cabin layout was one of the best.
The lounge is well appointed with floor to ceiling windows that provide a panoramic view, from seating areas that included swivel chairs and sofas. The lighting and music were perfect and made for a very comfortable place to hangout while cruising or in port. The upper deck is huge and comfortable.
The dining room was large comfortable and luxurious. The wait staff was attentive and the food as good as I have ever seen on a ship. The theme of panoramic windows continued in the dining room and made for beautiful views while dining
We cruised with a gentleman that was very prone to sea sickness and he reported absolutely no problems at any time.
The only down side to the cruise was the shore excursions which we found to be too "quick" Mostly walking tours with local guides they tried to see too much too fast which was not for us. I should have anticipated that six stops in six days would only allow for the most cursory visit to anything but we were looking for a cruise and not a tour and that is what we got. We were treated to a sunny warm day for our afternoon on the Middle Rhine and this is some of the most beautiful scenery
Beware that internet connectivity was slow and at the busiest times almost unusable. The link is provided via satellite and the baud rate was painful.
