Oh dear. Why do people go to Hawaii except to surf, swim and lie on beaches?
Seems a strange place to go to discuss monarchy.
We go to Hawaii every year. We visit our friends, sight see, snorkel, hike, and relax. In addition to beaching, swimming, and surfing.
Hawaii has the only royal palace in the United States. It can be toured. A great deal of royal history can be viewed at the Bishop Museum in Honolulu. In short, it's probably the least strange place to discuss in the US.
