How often is Zak actually at the museum

An employee told me he is there everyday except when he goes on locations to film. I missed him being there by one day when i visited.

I went Saturday 6/9 at about 3:00 and he was there. He made his presence known but he doesn’t say hi. I saw him 3 times

My guide told me the museum isn't aware of Zak's schedule and pops in and out as he pleases. I'd advise following his Twitter; Zak tends to give hints on his whereabouts on there.

I was hoping to see him today but i didnt.

2 days a week.
