No - your tickets can only be amended to a date or time that is later than your original booked date or time.
If you are running late, not to worry, our admissions team will allow your party entry on the next available time slot.
Please note last admission is one hour prior to the closing time advertised on our website. If you arrive at the last admission time you will have 1 hour in our attraction. We cannot allow entry after the last admission slot.
