How did you confirm this? I didn't see any mention that pitch tickets are CC entry. It specifically says CC for a lot of other venues, but I didn't see it for Croke Park.
Hmm that is frustrating. It did not state this anywhere on ticketmaster.ie for Croke Park. I bought a pitch 1 ticket because I couldn't find a pitch 2 ticket. Then after another hour passed, I was able to pull a pitch 2 ticket so I bought it with the hopes of being able to sell the pitch 1 ticket. If it's tied to my credit card, this is a major problem.
