We took this cruise in October and it was wonderful. Excellent weather and some of the best scenery ever. The old German towns were magical to walk around and Amsterdam and Vienna were fantastic, Still the prettiest section of the river was the Wachau Valley. Castles Galore and vineyards too plentiful to count. Picturesque towns and beautiful old churches line the river. A real Bucket List item everyone should get a chance to check off.
