To change your pick-up time with Sixt, you can typically do so through the online booking management system on their official website. When visiting the Sixt website, look for the "Manage Booking" or "My Sixt" section, where you can enter your reservation details. Depending on the terms of your booking, you may be able to adjust your pick-up time directly online.
If online changes are not available or you prefer assistance, it is often recommended to check the contact information provided on the website and reach out directly to Sixt for further help. They can guide you through the process and inform you of any potential adjustments or fees that may apply. Always be sure to make changes as early as possible to ensure the best options for your rental experience.
