the earliest flight back on Sunday is at 7am (ouch), the next flight that is $48 is at 3:40pm. If we were to take a flight back to be there in time for our next flight, it would be at 7:39pm.
In terms of rental cars... let's see:
-renting a car from Kona Airport: $194.19 from Tues. to Sunday ($39/day)
(it would cost the same as if we rent from somewhere else in Kona)
-renting from 16th/17th from HNL would be $36/day
