We stayed at AKL and never saw cars in the driveway or had to wait for anyone. That said, while we had actually rented a car, by the third day, we just started taking the bus. It was just nicer not to have to worry about driving, parking, riding the parking lot trolly, having to get on the monorail or boat for MK, etc. The rental car sat in the AKL parking lot, untouched, for the last 5 days of our stay. Next time, we are definitely going to use Magical Express and just rely on Disney transportation the whole time.
