Even though this river cruise is way off in the distance (to say the least), I'd love to hear about the places that you found most special - whether they were on the published itinerary or not. Even if you found just one aspect of a visit particularly good, please feel free to share.
We'll be on the MS Harmonie. There's really no info on it, as it is yet to be built, but understand it is the sister ship of the MS Lumiere.
We did our first river cruise in 1993, with Tauck, a 2-nighter that was part of an Austria, Germany and Switzerland land tour (even recall our great tour guide, Charlie).
Our next river cruise wasn't till 2025, "Romantic Capitals: Prague to Paris," which was an absolutely marvelous trip.
