Certainly. Sixt offers flexibility when it comes to modifying or cancelling your reservation. You can make changes to your reservation, such as adjusting the rental dates, vehicle type, or pickup/drop-off location, by accessing your reservation through the Sixt website or app. It is advisable to review the updated cost before confirming any changes, as modifying your reservation may impact the rental rate.
If you need to cancel your reservation, you can do so online or by contacting Sixt's customer service. However, do note that cancellation fees may apply depending on the specific cancellation policy and timing.
