I understand that it would be the difference between the two ticket prices but would it be between the price of my grandsons season ticket seat, that I have paid for him and a normal adult season ticket or his u16s season ticket and a normal adult ticket bought as a 1 off, as there is a considerable difference between the two.

I don't know the minutia - for individual queries it would be better to contact the ticket office.
