Did not take a tour on recent visit, as we are not really group tour people.
Will say: Queen’s Jubilee Galleries are probably the best £5 I spent on the trip as far as sightseeing (close with the Ham & Cheese croissant at Gail’s overall).
Did also have a chat with a verger in the Henry VII chapel about the Order of Bath and the quire, which was a massive information dump, delivered genially.
The more time you can spend in a cathedral, the more you can learn and see, and appreciate what there is. WMA has nearly 1000 years of continuous history, with harmonious architecture that I don’t think has a parallel in a cathedral of its age. We were there for two and a half hours, and had it not been a mob of milling people to parallel Saint Peter’s in Rome, I could have stayed another two. But then I’m the “never skip the cathedral” guy.
