Discount Car Rentals operates from 9 AM to 6 PM, while my pick-up and drop-off times were outside of these hours. To pick up the car, I followed the instructions to find the 'phone wall' inside the airport and called the two numbers provided. The car rental office is about 2 km east of the airport at a parking lot managed by an agent, which seems to represent several car rental companies. They sent a large Iveco to pick us up and take us to get the car. Since it's an agency, they only checked the passport and the rental document from QEEQ, then handed over the car. There was a vehicle damage report sheet, which was fully marked. The car had a full tank, so I drove off without signing anything. For the return, I refueled at a gas station within 3 km of the parking lot, drove to the parking lot to find the agent, and they helped us pay the speeding fine on their computer. Afterwards, they used a large vehicle to take all six of us and our luggage back to the airport. It's been 14 days since the car was returned, and I haven’t received any charges for repairs or violations, so I believe the rental has ended smoothly. Hence, I’m leaving this detailed review.
