Amazing place to visit (particularly on a hot day (it’s a constant 15c inside) and astonishing to realise how big this building was. Our guide was good but the information given was a little repetitive and the tour felt rushed. There is so much to see but you are shepherded from one point to the next very quickly. We brought up the rear of our group and loitered taking pics and looking at the incredible rooms / bits of fresco, and that worked for us. The VR was good. Think we’d have preferred being able to wander through in our own time, guided by info boards, but maybe that will come in the future.
