First time I've used Costco Travel to rent a car. I had already reserved a car with Discount Hawaii Car Rental, as I've always been happy with them. However, after reading so many posts about travelers using Costco, I decided to see what they had to offer for a pickup in Kona and a drop-off in Hilo. I was pleasantly surprised that I could save $90 with them ($289 for 10 days). I think I got a good deal. Thanks, fellow TA posters.
