I had a 4day break there ,it is worth a look as has been said did the harbour tour but also found a coach tour of the docks it took about 3.5 hours went round the container terminals ,right in among the ships and cranes ,had a break in the sea men's mission ,the seamen among you might remember the name it has duck in it some where . The only down fall was the guide only gave the commentary in German.When I returned home I contacted the company to tell them this ,Two days later I received a typed transcript of the tour so all in all a good result. I found the tour on the web and booked it all worked very good ,even the wife thought the break was worth it .
