Go to their website and make a reservation. Keep in mind the car shortage is still hurting rental car places, so you probably won't get the exact car class you reserve, but they won't charge you an upgrade fee if they don't have your specific car class. This does not apply to wildcard/manager's special options, as those could be literally anything with wheels.
We reserved a car online. That was the best way to make sure there was a vehicle available and knowledge of the price.. As of February 2022 the car rental parking lot at Myrtle Beach International is under construction. You will have to walk a ways to get your rental vehicle.
