The walk was amazing and actually quite surreal. While I can't pretend that I've never stayed up all night, this really was a new experience. The walk was affiliated with Open House London and enabled walkers to visit various iconic buildings en route. The first was City Hall at 8pm, followed by a ride on the London Eye. We arrived at Fulham Palace around 3am (tea has never tasted so good) and got to Battersea Power Station at around 5am. This was amazing - a real privilidge to be able to go inside and see the fantastic light and music installation. We arrived back at Potters Fields near Tower Bridge at 7am. I walked an extra mile to get home and had the best bath of my life!
