First, it is enjoyable, and you should go. Second, it is a little bit of a public history anomaly, which might make it more interesting.
Nelis Dutch Village is described as a completely rational extension of the tulip farm that the Nelis family owned and run in the first half of the century. As you ramble through the tulip gardens, you are greeted with distinctly dutch looking buildings, attractions and artefacts. It is a celebration of Dutch culture.
But the interesting part is it is a celebration of just Dutch culture, not Dutch American culture (besides the Nelis family history). The mandate of the park seems to be to bring a part of Dutch culture to the United States. But then again, apart from some artefacts like an amazing player organ, they things they are presenting are not Dutch, but in fact just in a Dutch style. Like there are buildings and costumes from different provinces in the Netherlands, but none of them were made in the Netherlands, just in a style that is identifiably Dutch. And it is a bit of a rag tag representation as well, basically what nineteenth century antiquarians collecting people's national character would consider truly 'Dutch.'
Skansen park in Stockholm. In fact, this is, according to Skansen, the model for all of these history parks which present a nineteenth century nationalist view of nationality. And Skansen owns up to this part of its history. But the buildings brought from all over Sweden are just that, actually buildings that are now being preserved by Skansen. The Nelis Dutch village is not preserving artefacts as a result of a nationalist impulse to preserve culture. It has skipped the preservation part and gone right for the nationalist impulse.
Like Skansen, the Nelis Dutch Village also has some turn of the century rides and a park, which I think most health and safety officials would balk at. For instance, they have a sort of small zipline which is unmanned, so it is simply up to parents to keep their kids safe, and I did see one kid tumble off the 4 ft. high platform while I was there.
Sinterklaas and Zwarte Piet is controversial when it doesn't need to be, because Zwarte Piet is and should be a controversial thing to American audiences, but an interesting (maybe slightly controversial) part of Dutch culture, that is not being adequately explained here. It is just presented, without comment and without much information, so that all it looks like is that slavery is condoned in Dutch culture, which is totally inaccurate. The museum does not have much, but shows the nationalist impulse that drives the park by showing only old customs and images of the Dutch royal family.
