Cars seem to be particularly cheap in Hawaii this year, so be on the lookout to save money -- and check back periodically after you book for even a better deal, since the rates keep coming down. Orbitz seems to be a good place to start comparison shopping.
greece and egypt combination tour As an example, I now have a 1 week full size rental from National at the Kona Airport greece and egypt combination tour for a base rate of 119. They gave me an additional association greece and egypt combination tour discount of 17 and allowed me to apply a 20 off coupon from the Entertainment Book . So that s now only 82 (+ tax and fees, of course) for the week. I ve never seen car rental rates that low in Hawaii.
FWIW, rentals in Kona seem to be the cheapest in Hawaii right now, but Maui and Kauai rentals are almost as inexpensive. Honolulu rates are also reasonable, but seem better by the week than by the day.
The only cars that aren t cheap are minivans and SUVs. So if you positively have to have one, maybe priceline bidding makes some sense. We ve had some reports of minivans going in the mid 20s/day through priceline.
I actually found a convertible cheaper in Maui than I did The Big Island. greece and egypt combination tour You just have to shop around and if the prices are high, wait. My advice it to check back often. I have had prices change with rental cars with in hours of each other.
Check the car rentals board here. In Maui and Kauai, greece and egypt combination tour there have been some GREAT weekly rates for convertibles. After using my coupon, my daily rate was 31.98 for a convertible from National (Sept 06).
