Visiting Hawaii (Oahu) first thought of Waikiki Beach, or Mona Mall, Alabama. You should check out Miyagi in the city center to see how Hawaii became the 50th state in the United States. I highly recommend a guided tour, learn more than you do yourself. You can also visit the King Kamihamiha statue, the state capital, the palace next to the Governor's Mansion. Another suggestion is to use public transport, the palace is just across the street from the bus stop.
