Cars is very smooth good acceleration for the size. Can fit 4-5 adults comfortably with a few bags in the back. Roomy back seats beats a compact/mid size car.
Majority of the time I will leave the car at fastpark&relax the day of or day prior if the reservation is made for RDU airport, it's usually 8.50 to get the car out of the parking area, I have found that this is the most convenient option for both parties given flight delays and tardiness. I will text you instructions on how to get the car once I drop it off. Then upon return you can leave it in the same parking area and I will pick it up. If I'm available I can meet you and bring you to the airport at the end of your trip. Please let me know if you have any questions.
