I did some checking for you (i live in Kona) and found that 30 a day for midsize is about the going rate for the "better" rental companies in kona. At this late in the game, your better off sticking with that. When I drove by Alamo yesterday, ( a friend came into town), the line was out the door. Thrifty was so so, National was busy. Budget was busy, Avis was pretty empty as well as Hertz. So in retrsopect, you may get what you pay for. Long lines and cheap rates. Short lines and slightly higher rates.
