My (later) wife and I visited Amsterdam in 1969 and had a great time. We went on the Amstel Brewery tour which I can strongly recommend. One young Swedish lad there, who was obviously an old hand at this sort of thing, reckoned that the Heineken tour was better, but that was over 40 years ago. We didn't sober up until later in the afternoon at the zoo. I have absolutely no idea how we got there. http://madeinatlantis.com/amsterdam/brewery_amsterdam.htm
Times have changed.... we went by train from Enfield Town to Amsterdam Central via Hook of Holland. My dad got me a free pass but my wife's ticket was just over £9 return.
