We commenced a 14 day cruise starting from Cologne and due to finish in Budapest. We were oblivious to the low water problems before we left. It was obvious from day 3 that there were serious river level issues. Perfect Recipe for holiday stress. We received conflicting updates , missed 2 itinerary stops , had the Nuremberg visit seriously shortened and then didn’t cruise any further from day 7 being moored near Straubing. We were taken on some time filling bus trips until finally the axe fell and we were told by the cruise manager that the trip was being curtailed and we would be flown home from Munich. We were duly despatched from the ship at 4 30am We never got to see Vienna or Budapest. This trip should never have been allowed to commence with such uncertainty and by running it and ruining it we won’t get the opportunity again to visit those special cities. This was the most expensive holiday we have ever booked and was a total and absolute calamity. We were the victims of indecision and procrastination for had the trip been cancelled at least we would have had the opportunity to re book .
