My wife and I will be renting a car from Dollar in Orlando and returning it to Miami after 2 weeks. I’m all set with the reservation, but I have a question. Is there any problem with my wife also driving it if I only registered it under my name? In the past if I indicated a second driver (only available at the desk, not on-line when I reserve it) we have to pay additional daily fees (about $15/day). I’ve usually not opted for the second driver and thus only drove the car. Can't a spouse drive a rental car without incurring an extra charge? What happens if my wife drives the rental if she’s not listed with them as a second driver and something happens? We’re both on our car insurance policy and will pay with Discover which is also both our names, but not opting for the company's insurance.
