Don't know what part of the ground you use, but the E2 turnstiles for Holmesdale Upper, we scan our own cards and nobody else even looks at them to see if they are adult or child, so nothing stopping it even if they have withdrawn it

No idea about other sets of turnstiles though, some of those in the Main stand are very old fashioned

We sit in lower Holmesdale, no-one looks at the tickets

My understanding is that my contract with Palace works both ways - They give me an opportunity to watch league action; I need to ensure that my seat is not left empty for a game. Should the game be an evening game - and they are getting later - I have had a choice, on a child ticket, of deferring bedtime or taking in an adult friend. Full terraces inspire our team, the Box Office needs to let extra adults (who could buy their own season tickets next year) to have match experiences. COYP

Last time I had this issue I had to pay the difference, and as it was a bundle I actually also had to pay the difference on the first game where the ticket was actually used by a junior. So in fact was punished twice. Would make you think twice travelling for a game for 7hrs one way.......
