Overall the cruise was very disappointing. Due to the low water in the Rhine, the ship was not able to dock at any of the ports on the itinerary. We were bused to all the cites which took away from the convenience of getting on and off the ship during the day. We did a ship swap on the 3rd day and spent 8 hours on a bus getting to towns and the next ship. For 4 days the ship was docked at a commercial area near Cologne, Germany along with many other ships. The ships were all joined side by side together – at one point we were 4th in a group of 6. When we opened our cabin curtains all we saw was the side of another ship, or the inside of someone else’s cabin. Could not use the balcony! I know that Viking is trying to do their best with the low water situation, but in my opinion the best would be to cancel the trips until the water levels are back up. Its not right to pay for a cruise, but receive a bus tour.
