We just returned from our week long trip and we rented with D&D Car Rental. I had seen quite a few questions in posts before we left so I will post a quick review.
First they are a local company. We rented a mid size with them. The cost was slightly higher than the cheapest economy size car, but it also included the CDW and was much cheaper than the cheapest national chain midsize. They picked us up at the airport, drove us to the Renaissance hotel in our rental car. They will also give you a free cell phone to use if you request it. The car was a new Yaris, in great shape, it drove great and got great mileage.
Unlike a previous local rental car company we used on another island, D&D had all the paperwork and insurance in the glove box.
At the end of the trip they picked us up at the hotel and dropped us at the airport.
It was by far the most simple rental I have ever had. The driver was very nice, and the transaction was quick and easy. And the pickup and drop off service was very convenient.
I highly recommend D&D and will definitely use them again if we go back.
