To enable people to gain quick entry to an eisteddfod venue rather than queuing up at the front desk - or for those who do not routinely carry cash - it is possible to purchase a single day ticket for one or more people, using credit card or paypal.
The calendar lists the various sections on that day. At the top right hand corner there is a green button entitled "BUY TICKET". This will take you to the standard shop page where you can buy whatever category tickets you wish - adult, concession etc. Note that admission prices do depend on venue.
When you have completed the purchase you will receive a confirmation email with the details of the purchase - including HALL and DATE.
Either print this out or have it ready to show on your phone or tablet. Present this to the volunteer on duty at the front desk.
