Yes, I was also overwhelmed by all the options and thought it would be easier to access the smaller venue options. I did the Crystal Palace Subway, which was very interesting and informative. I am surprised that it continues to be boarded up; I could imagine the space being used to hold events and cultural activities. However, the tour was a bit underwhelming for me because I had expected to have access to a real subway system, a bit like spelunking or something, which the tour was not. However, the building exhibits beautiful examples of brick and stone craftsmanship and I am glad that I was afforded a chance to see it.
