I am presently going through the guide/docent training at the Academy. With the opening less than a month away take it from me, you certainly don't want to try to arrange a private tour prior to September 27th.
I'm with Dyngoe. Even then we should wait until the dust settles.
After a couple months, the staff will be more inclined to give us a "special" behind-the-scenes
tour. I can't speak for The Academy; just my opinion.
Until then, if you want to get an early look, join up and get the official invite for the members tour (RSVP required). I'm sure you'll all be impressed.
