Long term airport parking safe?

[macuu222]

We had a trip from Kona to the mainland for 3 weeks. We rented a car at the kona airport for $25.00 the day before...drove back to Hilo....then drove back to Kona to return the car the next day when our plane departed. On the return....we got a rental in Kona for$40.00 a day and no drop off charge to Hilo. Total was less then $100.00 including gas. Cost if we were to park our car at the airport.... $320.00
