Travelers want flexibility, which is why we offer free cancellations on most car rentals. If your Kaiser Permanente Hospital Riverside plans change, just log in to your account through the
Trips portal, select “manage booking” and then choose “cancel this car.” Flexibility is just the start of the reasons to book a ride with Expedia. Combine your accommodations, flights and car into a vacation package and save on your entire trip. And that means more money to spend on sightseeing, food or whatever you like!
