I think so but call frist
At the airport site you can schedule it for less money. Last year it was about 6 bucks per day (that was the cheapest one). Go to https://www.rdu.com/parking/ and schedule your parking. It tells you how much you'll have to pay.
Sorry now clue but you should be able to contact the airport and reserve a space for a fee.
You can not sure how much
