I had to go to Oahu between Christmas and New Year for my Green Card renewal. The tickets from Kauai to Oahu were just slightly more expensive than going to California at other times, and the rental car would have cost more for a day than usually for a week. (I walked and took the bus). INS was friendly and fast, the breakfast was good, and then I walked all over town, visited the Iolani Palace and several museums and had dinner with Francine.
