After I researched, I found that yes. The DD214 is proof that she was in the military, and will work there. Also, the veteran stamp will work aswell. So long as it has the V. It's fine. Also, just so you know, I did call and this info is straight from the Zoo itself. So don't worry about it. And have a great day.
Yes that will work take the DD214 with you.
Drivers license with stamp is sufficient
