Season ticket upgrade

Does anyone know if I can upgrade a child season ticket to an adult for today's match.

Ticket office will issue new ticket for you with the extra cost

Will the price be the difference between each price or will it be a full adult price?

Haven't done it for a few years but it can end up pretty much full whack although they used to be a bit inconsistent. They charge full whack and take off the what you paid for the ticket which in the case of a child season ticket can be very little. The time before the upgrade cost very little. As I said it was a few years ago.

I asked a steward and he said oap tickets don't show as being different from full adult only kids show different! Guess best way is to just do it see what happens?
