Your morning sightseeing with a Local Guide includes all the famous landmarks: the Houses of Parliament and Big Ben beside the River Thames, Westminster Abbey, Whitehall’s mounted horseguards and the Prime Minister’s Downing Street, Piccadilly Circus, and Buckingham Palace. Highlights are a visit to ST. PAUL’S CATHEDRAL and the ceremonial pageantry of the Changing of the Guard, if held. This afternoon, why not join an optional excursion to the Tower of London or Windsor Castle, and later, maybe an optional dinner followed by a cruise on the River Thames? (Breakfast)
