This was a Danube cruise, Budapest to Nuremburg. Due to low water on the river, the ship discharged passengers just beyond Regensburg, busing those who were departing from Nuremburg and to Prague for those who had signed up for it.
At this, we considered ourselves fortunate, because we heard that some other cruise captains refused to go on past Vienna. Ours did go on, although it was disconcerting to hear the cruise director offhandedly characterize our situation as "precarious."
The Wachau valley, through which the Danube flows, is beautiful, and we had practically cloudless skies to appreciate it. The several little towns visited along the way bear enough resemblance to each other that they ultimately became indistinguishable and of marginal interest.
