We are cruising through Slovenia today, on our way to Vienna. The river does appear low but I believe I only noticed it because I’ve been following along with this thread…
During our daily ship talk, the crew told us there is the probability we will have to ship swap at Passau, but that the decision comes from Viking corporation in the end. I imagine the logistics must be quite complex considering all the ships and ports. We are having a wonderful time and even with a ship swap, it’s a minor interruption.
As for some speculation that many would’ve cancelled had they been warned, I had bought trip insurance that allowed cancellation for any reason and I still didn’t cancel. I was going on vacation hell or low water😂
So for me, as much as it is very important to be informed and know what you’re getting into, and as fascinating as the water levels, locks, and bridges all are, I would not let it deter anyone from going on this cruise. At least, this Viking experience, anyways, has been very carefully executed. Hope this helps
