Our flight back home is leaving out of Kona around 10:45pm. We have to check out of the hotel that day around noon. Is it safe to leave our luggage in the car as we explore Kona and maybe some coffee areas? Do people pay for an extra night and just check out late on the night of the flight? Are there beaches with showers? If so, is the luggage safe in the car? Suggestions on what to do?
