Travelers want flexibility, which is why we offer free cancellations on most car rentals. If your Hallasan National Park plans change, simply log in to your account through the
Trips portal, click “manage booking” and “cancel this car.” Flexibility is just the start of the reasons to rent your wheels with Expedia. Combine your accommodations, flights and car rental into a vacation package and save on your entire escape. And that means more money to spend on the important stuff, like having fun!
