Instructions:When you log onto the website click on book now. If you are planning on booking the tickets online click on 'Book tickets now' and then enter the code WCDM3 where it says 'If you have received details of a SPECIAL OFFER, please CLICK HERE first to log in'. Once you have entered this code chose the day you want to go and continue as normal. If you are planning on phoning for your tickets quote the code CDM3. I tried to book paltinum passes too but they are all sold out for each day so don't waste time book straight away.
