St Paul's was very interesting; hadn't been there for years. We got some nice little triangular sandwiches and free orange juice, an excellent guided tour, and all the free time we wanted to wander round - I amazed myself by climbing right up past the whispering gallery to the top of the dome, which has great views. No doubt the last time I'll ever be able to do it.
I still haven't figured out why I was there. On previous palace visits I think they've mistaken me for a group tour organiser (I've never been anything remotely like it) that they want feedback from, but this time they didn't want to know anything, just told us to have a good time. Nice to have little freebies like that land in your lap.
