  1. I used AutoSlash recently and after 7 (!) price drops in about a month and a half they saved me over $200 on my rental which ended up being more than 40%. At one point they even upgraded me from an intermediate car to a fullsize since that was where the deal was. Couldn’t be happier, especially since Avis treated me really well even though my rate was ridiculously low.

  2. Try renting out from the locals thru Relayrides.
    I personally use this site to rent out my vehicles in Big Island and met wonderful people who took care of my car like it was their own. This also helps the local community:)

    1. Hi Alice,

      The insurance and liabilities associated with Relayrides found via Google search sound quite daunting. Buyer beware – do some research.

      Aloha.

  3. We are sailing on the Pride of America this summer. Does anyone know of a company that offers a package deal with a rental car at every port?

  4. I normally rent cars via Costco’s travel website online. Great rates. But one trick to remember when renting cars. The airport car rental locations usually include a MUCH higher tax rate than renting off-airport. I recently rented a car through Costco for Oahu and shopped the various rental locations available. I found one that was literally just offsite from the airport. You have to take a quick taxi to get there but even with that, I saved a huge amount. I also got a great deal through Costco for Kauai.

    The smaller Hawaiian island car rentals probably don’t have options outside of the airport ones. But remember this tip for bigger city car rentals. I paid UNDER $100 for an entire week in San Francisco, renting just outside of the airport, using Costco. And I drove an SUV (was upgraded).

  5. I’ve always used priceline when booking a rental car in hawaii, I’ve had great success booking on all the islands, booked a camaro convertible last September on the big island for for $249 for 7 nights thru national, over half price from their own website, I’ve won bids from budget, hertz, and national rental company’s,

  6. Costco’s American Express credit card offers rental car protection that is among the best. Renters have been denied a claim even though they used a credit card that offers rental protection because they didn’t purchase gas for the rental car using the same credit card. Just to be sure, charge your gas purchases using the same credit card that you used to rent the car.

  7. Book the smallest, cheapest car they have.mThey almost always run out and comp you up. We’ve booked an Aveo @ HNL and driven out in a convertible.

  8. I typically make my initial reservation at Costco. But after you have a confirmation number, here’s the secret – go to autoslash.com and enter your confirmation number, rental company, and departure date. Autoslash then continually monitors the rate and alerts you if it goes down.

    I’ve saved a ton of money on not just my Hawaii rentals, but other vacation rentals as well. I’d say that 90% of the time, Autoslash has lowered my rate.

    One thing to remember though is that if you booked through Costco and then rebook a lower rate through Autoslash, you’ll lose the free second driver that Costco reservations allow. Also, I never book initially through Autoslash; I figure that gives them incentive to find me a lower rate. 🙂
