You need to get here early in the day if you want to see the Crown Jewel's. If you buy your tickets in advance through a concierge at your hotel you will skip the big line for tickets and go right to the group sales section which had a very small line each time we were in the area. I recommend the Yeomen Warders Tour which runs about 45 min. Another must see while in London.
