Does anyone on this list work at dynamicland?

I tried to visit last time I was in San Francisco and it turns out this thing is closed to the public. The guy who answered the door says he's not sure when the next open house will be, no one is answering the "contact" page and I'm not getting any email announcements on it either.

Is there ever going to be any "open house" when any joe schmoe is able to visit?
