I went to London this month on business for Reuters.  On my first day at the Canary Warf office on the East End of London, the Queen paid a visit and filed a news article.  I spent most of my time at the office, but managed to see a little of the city from the car ride from and to Heathrow.  The Hilton hotel was across the Thames from Canary Warf but there was a ?Hilton clipper? that connected the hotel to the Thames Clipper dock at Canary Warf.
