Flew to London from Reykjavik, found it to be a HOT day in London, took a car service to Greenwich Pier to check into and board Viking Star. Met Anne for dinner in Greenwich and explored around the Old Royal Naval College area. Next day, explored London on my own (Howard went to the Observatory) and we both went on a London overview tour that Viking provided. The ship sailed down the Thames at 7:30, through the Thames Barrier, and out to sea.
