Its a question in the Travel section of the Sunday Times. In fact it is fairly difficult to work out, but I did it and will post the answer on Wednesday if I think of it (as I would like a free trip to Norway myself !!!)
Sorry not to have come back earlier, but I do not look in on Answerbank very much now that it has changed. I expect that you subsequently solved it yourself - Erraid is the answer - the link tells it all !!
