We prepaid and got a Nissan Pathfinder. It's quite large, similar to a full-size SUV. There were two of us with a child, and we managed to fit two 30-inch suitcases, one small suitcase, and a stroller in the trunk. The car had some scratches and a slightly damaged front bumper when we got it. We took photos and confirmed with the counter staff that these issues were noted in their system. Before picking up the car, the counter staff tried to sell us various additional services. They also mentioned that there is only one gas station on the way to Oahu airport which usually has long queues, so we opted to return the car with a full tank. In the end, we only used half a tank of gas, and we saw two gas stations on the way back with no queues. When returning the car, make sure to navigate to Dollar Rent-A-Car and not follow the rental car return signs for the airport, as Dollar is not located inside the airport. We drove around quite a bit before finding it. Make sure to return the car early and allow some time to wait for the airport shuttle.
