Being flexible is important, which is why Expedia offers free cancellations on most car rentals. If your Alviso Marina County Park plans change, log in to your account through the
Trips portal, select “manage booking” and then choose “cancel this car.” Flexibility is just the beginning of the reasons to book your ride with Expedia. Bundle your hotel, flights and car rental into a vacation package and save on your entire getaway. And that means more cash to spend on having a great time!
