Great historical place. Depending on when you go, it might be quite crowded. We went in mid April, but the fast track tickets that we got with the London Pass really helped since we bypassed the long line outside. In order to have an enjoyable experience, I'd recommend getting in early, and finish seeing the crown jewels first since that gets crowded later. Definitely take in the beefeater tour.
