Frequently asked questions

What happens if I need to cancel my Great Diamond Island car reservation?
We all have times when even our best-laid plans get upended. That's why we give your money back on many prepaid bookings if you let us know a minimum of six hours prior to picking up the car. Don't forget to double-check the policy — there are some instances where it's not offered. Found nothing there? Our Customer Service Portal is always here to help.
How do I find the best car rental deals in Great Diamond Island with Expedia?
Check out reviews and ratings, choose your preferred ride and compare offers from leading suppliers. Expedia makes it easy to score the best deal on your rental wheels. Combine your Great Diamond Island car rental with flight or hotel bookings and cruise off with even greater savings.
How old do you have to be to rent a car in Great Diamond Island?
You need to be at least 21. But there are several age-related requirements you should keep in mind before you book your wheels in Great Diamond Island. If you're a younger driver, most rental companies will charge an additional daily fee and limit the kinds of cars you're able to rent. The amount of the surcharge, and which age range it applies to, varies between companies. It's a good idea to compare the requirements.
What do you need to rent a car in Great Diamond Island?
Two things — a valid driver's license and a credit card in the same name. Car rental companies will offer you insurance, which is optional. But you may be asked to provide proof of other coverage if you choose to opt out. Check with your rental provider to avoid any problems.
Can I rent a car for a month or longer in Great Diamond Island?
Yes. Expedia partners with reputable companies that offer weekly and monthly rentals for many car categories. Check out our long-term car rental deals and explore every inch of Great Diamond Island — or beyond!
Where can I find a Great Diamond Island car rental if I am younger than 25?
You'll need to check the age policy of the Great Diamond Island rental suppliers you're considering. If you're under 25 years old, be mindful that some will charge additional costs. It's useful to know about this in advance so you can have the funds ready. Each rental car company has its own policies for younger drivers, so do your research.
