Well, a river cruise is not an ocean cruise that was our first learning. It took awhile to get the hang of things as we are avid Ocean cruisers. There were a few places where I felt staff were non-responsive, especially when a gastro virus swept through the ship. There were more busses involved in getting to cities than we would have liked and we were uncertain as to why this was so. I don't envy the cruise director with all the ups and downs and daily changes to plans that I guess were mostly due to parking requirements, lock availability etc. We love the lock thing, 67 in all what treat.
