Does travel really broaden the mind? On the face of it, it's a no-brainer: you see how other people live, experience their cultures, get different perspectives on issues you thought were black and white and come home knowing the only people who take it for granted that this is God's own country have never been anywhere else.
But at least some of that mind expansion takes place before we ever leave home. We are, after all, responding to the lure of the different and we usually have some idea of what to expect. If you pitch up in Paris expecting it to be pretty much like Hamilton, you've probably embarked on your OE way too early or way too late.
Then there's the reality that, for most people, travel means going on holiday and you can do that in most parts of the world without leaving the cocoon of the westernised hospitality product. Vacation-land is much the same whether you're in Marbella, Martinique or Maroochydore.
Many package holidays seem designed on the principle of ticking as many boxes as possible in the allotted time, as in the 1969 film If It's Tuesday, This Must Be Belgium. As English cricketer Phil Tufnell said of touring India: "Done the elephants, done the poverty, might as well go home."
Mind you, the preoccupation with authenticity and getting off the beaten track is sometimes bogus in itself. I once went on a Caribbean cruise with a group of English journalists. On the last night, when we had to nominate our highlight, the others waxed lyrical about going up the Orinoco, a wide, muddy Venezuelan river winding through mile upon mile of featureless jungle.
