Within Oahu, Hawaii

There was clearly an orange car, but they insisted it was dirty. When I went back to take a photo to prove it was clean, they called security through the intercom to stop me. I was already sitting in the car, and they said I could upgrade and switch cars. If the car was sterile, why switch after I’ve already sat in it and then give it to someone else? That's so irresponsible and sloppy.

Friendly and convenient

The pickup was relatively quick, but the staff's attitude was mediocre. We had to queue up to explain scratches and other concerns, which wasted a lot of time.

Very good

There is a free Alamo shuttle right outside the airport with frequent service. The rental office has both self-service kiosks and regular desks with a short wait time. The staff member who assisted me was very friendly. He suggested I upgrade the car because I had 4 large suitcases. Although I had reserved a full-size car like a Ford Fusion, he offered me the largest car in the same category, a Chevrolet. I checked if my luggage fit, and it did, saving me the upgrade cost ($40/day). He also recommended adding roadside assistance for $5 a day, which is helpful when you're traveling. He suggested prepaying for fuel since there are few gas stations around the rental location (some are under repair, some closed, and some far away). Taking his advice, I prepaid, but it turns out it's better to refuel on your own. While the price per gallon was similar, the estimate of the remaining fuel wasn't precise. However, factoring in the labor cost of refueling, I went with the prepay option.
