I don't know if I missed something but there seems to be only one room of display. I understand the exhibits change as most of the collection is in storage. What there was was very well displayed and captioned in both English and Spanish.
We were met by a guard at the gate who told us in Spanish it was closed. That doesn't agree with what their website says. Since we couldn't converse with him, we didn't get any details. We were disappointed it was closed.
