I ve been on every trip I ve ever taken to London. Always memorable! We arrived just after opening and had virtually no line ups. Around noon I would estimate the wait to see the Crown Jewels was easily 90+ minutes.
The Yeoman Tours are the highlight and if you are one one that it s quite busy be strategic about staying to the outside of the group for the first and third stops. This makes it easy to get up front for the second and fourth stops.
