Oooh. Good question. it was quite a few years ago so has probably changed a lot since then as they were talking about opening up a beer hall or something in their future plans. We definitely went into the Italian families house and another with absent father, so looking at their website it's likely to be the hard times tour unless they've changed the themes since our visit. There were kids on the tour, about 9 years old and the educator interacted well with them without losing the rest of the group. They enjoyed handling objects and answering questions. We wanted to go back and do EVERYTHING there, but only made it down on our last afternoon so had to settle for the only available tour and the video/exhibition instead.
There seems to be a lot of information on the tour content on the website so you can make an informed decision about what would best suit your kids.
