Absolutely wonderful museum, we've been twice (2018 + 2019)! Come early and plan to eat breakfast + lunch here. Entry is free with the Swiss Travel Pass and it is on the bus line.
You can't really see all the buildings in one day so either plan a return trip (like we did) or do your research first and see the high points. Food is good and there are vegetarian options. If you are a fan of architecture/history/gardens then you will be in heaven. Our kids (12 & 14) really enjoyed it and there was regular spaced concessions so they wouldn't get "hangery". Loads of signage explaining everything, gardens everywhere, farm animals to be seen! You get to walk inside almost every building! Meet local Swiss docents doing traditional crafts (cheese, woodworking, rope making, pottery, baskets) there really is something for everyone! And there are opportunities to purchase crafts as well as food stuffs.
Buy the guidebook and bring it home, read it cover to cover then go back again!
