Yes, but you will need to call to let them know the new return day and time.
I believe you have to call the location you rented from and advise them you are planning to keep the vehicle longer.
Yes just call them and let them know u want to extend your rental.
I wouldn't worry about calling them if you need the car for an extra day. The cost of 1 day will be deducted from your $ depisit upfront, and your credit/debit card was authorized for incidentals over that. Whether you call ahead of returning late or not, it doesn't mater. Technically, returning the car after it's due would be breaking the original contract and they could jack the price up for the whole trip, but they won't. But for time over the original booking, the additional fees have additional terms that may not be in line with the reservation. In most cases each extra day is charged at the maximum day rate on that day, and will not be rolled into a weekly or monthly, no promotional rates or discounts are honored and you can't pay for extra fees with rewards points.
You have to call them & work it out.
