We are turning 50 and seemed to be the youngest on the ship so I thought the experience would be slower but that was not the case! We were able to customize our trip and wound up doing over 20K steps a day and stayed up later than usual every night!
Each day included a walking tour of the port—you can be part of it or do your own thing. The afternoon offers other excursions or strike out on your own. We did a mix. As per excursions, I highly recommend the Colmar WWII tour excursion. The guide was so knowledgeable and the stops were perfectly paced and interesting. We also did the Ehrenbreitstein Fortress tour which was led by a professional actor who was phenomenal! On our own we did the gondola ride at Rudesheim and spent a lot of time in the old city centers at cafes since the weather was so nice.
The food on board was incredible. Breakfast was both buffet style and cook to order. There were also local cheeses and flavors to try. Lunch and dinner each had mainstays on the menu, plus several different new choices daily. Also at dinner was a “local flavor” menu—I ate from that most nights and love it. I recommend getting to dinner when it starts to be able to enjoy the appetizers that the staff comes around with. Though the ship offered every meal, we also chose to eat on the street sometimes too to get a feel for the location. The ship offered a German food night and the selections were way better than any off-ship meal we had in Germany!
Our room was wonderful though there was a bottleneck at the end of the bed. We got the room with the step out terrace/balcony and we spent a lot of time there. We were on the starboard side (outside as we sailed up river) so we had a great view from our room. There was enough room on the terrace for two chairs and a little table. Since we were often going back and forth from the terrace or one side of the bed to the other side of the room (door and bathroom), the bottleneck at the end of the bed was a bit of a hassle but not terrible. If we go on a longer cruise we will do the upgraded room with the small living room—we peeked into one of those rooms and were impressed with how much space it added without going as ritzy as the Presidential Suite.
