In order to beat low water down the Danube, the ship rushed to Kamarom, Hungary, leaving tourists desiring to remain in Vienna with a bus ride to return to the ship, We opted to stay on board. Endured three heart-stopping passes below bridges within inches of the head. Cringing was allowed. Two massive locks followed, including what I was told was the largest lock in Europe. It was the largest I’d seen. Intimidating.
The ship can’t go any further. Tomorrow buses take us to Budapest. Some return to the ship, others (with earlier flights), spend the night on a local (landlocked) Viking ship. I can’t fault Viking for this arrangement. Some passengers, of (as I see it) questionable grievance thresholds, want to sue.
It was a relaxing day. The river was interesting, especially when our canal was disturbingly well above the surrounding land. Not many photos though.
Fishing outpost? Lots of them along the river. 
The Danube turns into the large lake at certain places. 
The driver of the ship, manning the port-side pilot station, needs protection from a leaky lock. 
Massive dock of the lock. 
The primary pilothouse. No rudder?
