JPL might be a good laboratory, but their Visitor Day Tour disappointed me.
The tour lasts 2.5 hours, of which about a half is spent on watching a movie about JPL. Then the visitors are brought into a small room from where they can look, through a glass, at an area where some apparatus are being assembled. That is, there is a big room with half-finished apparatus and other equipment and some people around working. This part of the tour takes a few minutes. The tour continues at a museum, where there are several models of various spacecraft, as well as life-size replicas of two Martian rovers (Sojourner and Opportunity/Spirit). Then the visitors proceed into a mission control center which is empty most of the time, so there is a large empty room with several screens showing some telemetry information. The last stop is a life-size replica of Curiosity rover.
Overall, I expected them to offer much more to the visitors. Ah, and you need to schedule a tour at least five months or so in advance.
