Went here on a alternately cloudy and sunny day in June, on a Monday so not so many people around. Started off sitting up on the top deck but quickly retired to the comfortable interior of the boat as the tour started and the icy wind picked up. Food and drinks available inside but we didn’t partake. Constant information is broadcast over the loudspeakers in several different languages, which became a background noise after a while. Not a really exciting thing to do, but interesting enough. Gives a good tour of the Port of Rotterdam and helps for the visitor to understand what a vital role the port has had in the making of this city.
