We enjoyed a large breakfast and after some good advice, drove to Egham from Windsor, parked for £6 in a commuter parking and payed the £18 each return rail fare to Waterloo Station. The train took less then 1 hour and had free wifi. The private train make a profit. Yearly trains cost are very expensive - eg £4000/yr for 8km metro commute. It's not uncommon to pay £10,000/yr.
We walked from Waterloo Station on a beautiful London day to Buckingham Palace, where the crowds were gathering for the 11:30 changing of the guard. Our walk took us over The Thames via Southbank Centre over the Golden Jubilee Bridge. We walked thru Embankment area to Trafalgar Square to watch the crowds around Nelsons Column
Dinner was with the Scroopes at the Beaumont Hotel. It had been a Jesuit birding high school from mid 1800s till about 1969. Interesting, Charlie Scroope from Canada has gone to school there after the war for 18mnth.
