Thank you coalminer! I should have provided the link, just I don't have that URL memorized.
I thought Hotwire was nonrefundable like Priceline. It's not? (cool).
I guess it is the golf weekend causing the shortage then, if the cars open up Monday.
There's a hula festival in Kailua the next weekend, not sure if it's a big draw or not.
"IOLANI LUAHINE HULA FESTIVAL - KAILUA-KONA
The 11th annual 'Iolani Luahine Hula Festival will be held on January 24, 25 & 26 on the grounds of Hulihe'e Palace and the Courtyard King Kamehameha's Kona Beach Hotel in Kailua-Kona."
There are car rental desks at the Fairmont and the Hilton, which is why I was asking where you are staying. I think there's one at the Courtyard too, which is where the cruise passengers rent when they come in to the pier. Maybe the off-airport locations might have one, if you haven't tried them yet.
