"Someone" got it right, you need to have a passport. A visa is only required for stays exceeding 180 days a year. You also need to book a return ticket. The Netherlands (the country) also has overseas territories, namely Bonaire, Saba, and St. Eustatius. They are considered regular municipalities, but you still need to have a passport to visit them. They also have some duration limitations to prevent migration from the mainland. About the governance: Long story short, it's complicated. Some laws apply to the Kingdom so they're for both continental and overseas, but most laws are made only for country of The Netherlands. The other countries are mostly self-governing, including making their own laws, but stuff like international treaties and military is done on the Kingdom level, which in practice means it's done by the Country. To give an example: after Irma, St. Maarten had to formally ask The Netherlands for help, otherwise the military would not have been allowed to give any assistance, as it could be considered an invasion. In general, any form of intervention is seen as a form of neo-colonialism. We try to intervene as little as possible.
