Being flexible is important, which is why we offer free cancellations on most car rentals. If your Greenbelt Shopping Mall plans change, just log in to your account through the
Trips portal, select “manage booking” and “cancel this car.” Flexibility is just the start of the benefits of booking a ride with Expedia. Bundle your flights, hotel and vehicle rental into a vacation package and you’ll save on your entire trip. And that means more cash to spend on enjoying yourself!
