On our recent rental, we had to get the full coverage insurance since we had gotten the family rate since my sister works at a car rental agency. I had learned from her that some insurance companies do cover your rental cars, but like the insurance that my parents and I have, it does not so we usually get the basic coverage. It may be a bit pricier each day, but it's better to be safe then sorry. If you get into an accident and don't have the coverage you will pay alot more. Plus, although you are safe, other drivers may not be.
