Pearl Harbor has been increasing in popularity for several years now. When we started out as an authorized tour provider, only the Bowfin Submarine and the USS Arizona Memorial were open to visitors. Visitors have steadily increased as more and more attractions opened.
In 1998, the Battleship Missouri was moved to Pearl Harbor and became a memorial the year after. It was a nice way to symbolize both the beginning and the end of the war. In 2001, the movie Pearl Harbor was released and more people in the US were aware of the history of Pearl Harbor. This is part of the reason that Pearl Harbor has increased as a tourist destination.
The opening of the Pacific Aviation Museum also started to draw in more visitors. Hawaii is already a prime location for a tropical vacation and the history at Pearl Harbor draws in tourists with many different types of interests.
