Unfortunately, Thrill Experiences is unable to make amendments to existing bookings.
Given that the operator will have already reserved a spot for you and potentially arranged logistics for the day's event, it is recommended that you contact them as soon as possible if you need to change the date.
To reschedule, please reach out directly to the operator. Please be aware, however, that depending on their terms and conditions, they may impose a rebooking or cancellation fee.
