This might be a British humoUr thing - as a local it read very much as a self-deprecating jab at our own English-centric travelling. Taken literally obviously it would be offensive, but it's not meant that way. I note that the author lives in Edinburgh, a place which has a reputation for quite dry, understated and self-deprecating style to start with - understandably, as the only way to stand the hordes clogging the Mile and other picturesque spots.
