Hotwire Hot Rate rentals are final and cannot be cancelled, refunded, changed, exchanged or transferred. These restrictions enable agencies to better manage their unsold rental cars, and that's a big reason why we can offer you great travel deals.
On the other hand, if you made a regular-rate reservation, you can cancel the reservation without penalty and create a new reservation with any car type you like. To cancel your reservation, log in to your Hotwire account, and click "My Account." There, you'll see all your activity including profile, itineraries, and saved searches.
