There have been stories about the IOC being dicks, but there were also stories about ghost town London. It didn't seem that way to me when I finally dared to cross the Colne. Then we find out that tourism stuff was indeed up, especially the West End.
Also, the beer festival I went to last week in Kensington, the venue was still called the Olympia, located next to Kensington (Olympia) station.
Though maybe it was the IOC what made TfL withdraw the District line shuttle to that station. Now that's a conspiracy theory worth talking about.
