There were shower and sleeping facilities available at the airport. My partner used them before continuing on with your flight. These services were eliminated due to security concerns.
Visitor information booths are located in baggage claim areas, outside the foreign arrivals’ area, in the Interisland Terminal, near Gate 22, and on both ends of the main lobby. Hours: 4am-1am, phone: (808) 836-6413.
