There have been a number of thefts from rental cars at Kua Bay and Kiholo Bay in recent weeks. The informal highway parking area where people leave their cars to walk into Kiholo has always been a problem spot. In many cases it is luggage that's being taken.
Just a reminder that no one should ever leave luggage or anything else of value in their car at unsecured locations around the island. If you want to go to a beach after check out but before a late flight, or otherwise have to have luggage in your car, go to one of the secured beach parks, like Kukio, Kikaua Point, or Kauna'oa at the Mauna Kea. Almost all Kailua Kona public parking lots are also a problem, so don't leave luggage or any valuables there either while you eat or walk around town.
