I just booked for arriving the day after Thanksgiving, and here are my tips for a 2 week rental star

Finding Hawaii car rental deals, like airline Hawaii travel deals, is a trick. With the recent consolidation in which Hertz is buying Dollar/Thrifty, it s going to get much harder to get a good price. Here are our updated recommendations:
In some states daytona beach fl hotels fees for an extra driver are not legal, but in Hawaii they are permitted. Determine if there will be a charge for this at the point of reservation, rather than getting stuck when picking up your car.
I would also suggest taking your reservation and placing it on autoslash.com. This site monitors your reservation continuously and if it finds a lower rate, it immediately notifies you by email. You could also make your initial booking there but I found the initial prices on Discount Hawaii Car Rentals cheaper though autoslash daytona beach fl hotels did alert me to a drop in price later.
I just booked for arriving the day after Thanksgiving, and here are my tips for a 2 week rental starting the day after thanksgiving it was $1200- daytona beach fl hotels at OGG- ridiculous for a compact! .however when I changed the pick up of the car 2 days later (monday), it went down to $400- (after daytona beach fl hotels the holiday weekend.)- saved $800- by waiting 2 days the cheapest I have found is hotwire cause you prepay. I think around busy times and holidays hotwire is the way to go as prices just continue to go up, not down. Off season you can check often other sites. Another suggestion is check JHM if your staying on the West side of Maui hotels will shuttle you there free .compare to OGG prices. I have booked at least 70 cars on Maui- and hotwire is almost always the best deal.
Good tips. My advice is to book early with a place or site that doesn t require a credit card to reserve the car, and check back frequently using different sites and discount codes you can search for online. For my last trip to Kauai, I re-booked about 6 times as better prices became available and saved almost $200 for just an 8 day rental.
