Do you charge for changing a car at 2 am ?

It depends on which company's car you rent. Yesaway is open 24 hours a day. If you pick up or return the car outside working hours, there may be a corresponding service fee.

As agreed upon by the car rental agency. Some offer 24-hour service, while others allow self-rentals where you can leave the keys in a box at the counter.
