Paul, that's nothing. I have a friend who went trekking round Asia for a month. On the way out, two of the group's luggage got left in Kazakhstan and subsequently followed them round Asia (is Kazakhstan in Asia?) for the next three and a half weeks, finally catching up with them in China two days before they flew back. Then on the way back, everyone's luggage got left in Switzerland for a month. So there were two people in the group who spent almost a month trekking round distant corners of Asia (Tibet, Kazakhstan and other places) wearing the same clothes every day.
Although personally, I'll also be avoiding the 2012 games. Too many people and too much London.
