You must contact us as soon as possible to see if we can extend your rental period. If we have a reservation for that specific vehicle we won't be able to extend your trip and late fees will apply if the vehicle is returned late. If you select a Late Return ($99) you can bring it back on your check-out day between 12-5 PM, but anything after that will be subject to an additional nightly charge. This HAS to be done before you check-in with the vehicle and cannot be done on the same day without an approval or there will be severe penalties.
