A must see while in London. Plan to spend at least half a day we did and I know we didn't see everything. Watch the line to see the Crown jewels, we waited till later in the afternoon and it got considerably shorter. We did not do the Yeoman Warder guided tour but have heard good things about it. American seniors the British use the word commission for over 65 pricing just beware. Buy the guide book everyone we got was full of excellent info and make a great souvenir.
