When I was a student we used to go on "Educational Trips" on the P & O Norland from Hull to R'Dam (famous for transporting 2 Para to the Falklands and Argie prisoners back to their place).
The trip was about 5 days with 4 nights in A'Dam (staying at the aptly named student Hotel Cok) the main educational aspect was the trip round the Heineken Brewery (now sadly closed and replaced by the Heineken Experience). We used to get totally wrecked over there and one of our girls was taken back by the matelots as a trophy to an RN Warship which was on a goodwill visit, they stuck her in a taxi later ! She now lives in Rotterdam and 2 years ago Mrs D & I went with her to Amsterdam and the former brewery - you still get a few free beers but it wasn't a patch on the old days when we had brutal size 10 hangovers from the night before.
Happy days
Have a good run ashore Arthur
