Dream journey

My dream is to do a journey to London with my friend. I would like to visit Picadilly Circus with it's famous statue of Eros. I would like to see Trafalgar Square and Nelson's Column and the clock-tower with Big-Ben, a large clock. My dream is to see Buckingam Palace, which is the residence of the Queen of England. It must be very interesting to watch the changing of the guard.
