Flexibility matters, which is why we offer free cancellations on the majority of car rentals. If your Miami Seaquarium plans suddenly change, log in to your account through the
Trips portal, click “manage booking” and then choose “cancel this car.” Flexibility is just the beginning of the reasons to book your ride with Expedia. Combine your hotel, airfares and vehicle into a vacation package and save on your entire escape. And that means more cash to spend on having a great time!
