Hi, all. My wife and I are considering a Christmas cruise on the Rhine or the Danube in 2025. The catch-my wife is somewhat disabled. She can comfortably walk about a half mile (round trip) and then her partially paralyzed leg gets stiff/tired, and she needs rest. So, would a Christmas cruise work for her? Is it a long walk to the markets? Are there shuttles? Is it all cobblestone? How doable is a Christmas cruise given our scenario? Thanks 🙂
