Last full day in London. Down the Birdcage Walk to Buckingham Palace. We had morning tickets to the Queen's Gallery and day entry for the State Rooms and the Royal Mews. Wow! Saw so much. Besides all the impressive rooms and paintings, they so have the wedding dress of Catherine on display, the wedding cake, etc. The Royal Mews were also interesting and the girls loved seeing the horses. Lunch in Green Park then off to the Museum of Natural History. What a beautiful building! The highlight was the dinosaur exhibit - amazing. Easy train ride back to our hotel.
