There's a check-in counter right outside the airport. After completing the formalities, I went upstairs to the parking lot to pick up my car, put my luggage in it, and drove straight to the hotel. It was really convenient. The price was reasonable, and the car was new, with only 18,000 kilometers. Having a car in Dubai makes it so convenient to get around, and most importantly, there's basically no parking fee. Kudos to the UAE.
