We know flexibility matters, which is why we offer free cancellations on most car rentals. If your Indiana Dunes National Park plans suddenly change, log in to your account through the
Trips portal, select “manage booking” and “cancel this car.” Flexibility is just the beginning of the benefits of renting a ride with Expedia. Combine your airfares, hotel and car rental into a package deal and save on your entire escape. And that means more cash to spend on sightseeing, food or whatever you like!
