We visited the museum with out three young children. They (and us) were duly impressed with many of the exhibits but on the whole the exhibits need to be upgraded and refreshed. They ought to be made more interesting as they all require lots of reading which was did not go down well with the kids.
The outside area showing different homesteads was impressive and would be of interest to children. But, perhaps we were very hot and tired (the air-conditioning is not very effective) from the tour inside, we just wanted to move on.
