Flexibility is important, which is why Expedia offers free cancellations on the majority of car rentals. If your Mount Tamalpais State Park plans suddenly 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 benefits of booking a ride with Expedia. Combine your hotel, flights and vehicle into a package deal and save on your entire trip. And that means more cash to spend on whatever your heart desires!
