We know flexibility matters, which is why Expedia offers free cancellations on the majority of car rentals. If your Greenbelt Park plans suddenly change, log in to your account through the
Trips portal, click “manage booking” and “cancel this car.” Flexibility is just the start of the benefits of booking a ride with Expedia. Bundle your accommodations, flights and vehicle into a package deal and you’ll save on your entire getaway. And that means more cash to spend on the important stuff, like having fun!
