I recently took a group of high school students on the gold vault tour. It was disappointing to me, and to the students. The tour begins with a 10 minute economics lesson (which was actually very good, but it was a lecture) and then you proceed down into the vault. The vault, which you see from a small foyer, looks kind of like an old prison. You only see a very small amount of gold, and it wasn't at all impressive to see.
