He does send a pdf of the window contents, with diagrams, after registration. He also recommends waiting in the rear pews until any services are done, if you are early.

I have attended this myself, and video'd it for my YT channel, and am sharing this FREE event for anyone who wishes to do it on their own. He seemed very flexible in letting anyone at all who walked in just join his tour, so I would suggest signing up if you can, but he did seem open to just show up people too. I will not be attending again, as I already have. NOT HOSTED by a MEETUP person.
