If you have received the error message 'No article for discount ID' it means you are trying to use the discount against another offer. Please close the ticket booking page and start again.
Choose 'Day Tickets' and then 'Blue Light Card/DDS Holder', follow through choosing your number of admission tickets, date and any other extras. Put your discount code in the box at the bottom of the page, and make sure you get the green tick.
Please note that BLC discount is applicable against our full price admission ticket of £32 and can only be redeemed on up to 5 admission tickets, ride wristbands are an optional extra. If you wish to purchase more admission, we recommend booking separately for the additional tickets.
