Thanks @Angie94 ! I loved--LOVED--the cathedral tour, and believe that it will not be available forever. It is not to be missed. I made friends with an American guy who was up there with a nice camera (much nicer than an i phone 6s, even though that's a pretty nice little set up), and I am really good at framing shots, so I framed, and we walked around and snapped photos together!
