Not sure they have considered every detail. If an adult cannot attend because their child is ill, birthday, holiday, school trip, at other parents, grounded - to name a few of 1001 reasons why kids couldn't make it. Then the adult has to surrender both tickets to an exchange, recieve no recompense, that is not going to sit well with many. Those tickets are then offered up for resale to prospective new or exsisting supporter who is struggling to get ticket??, Remember we are primarily thinking about midweek games, with school etc. How many new or exsisting supporters are going to pay full price for that ticket, maybe if we are top of league, what happens if we are mid-table, playing poor opposition, game on Sky and its raining, are these tickets really going to get resold, don't think so and there will be an empty seat for the camera's. As personally i will not go and pay full price for a ticket and sit elsewhere, in my mind i have already bought my ticket. So at this point the club has manged to secure one empty seat in stadium, great plan that, not forgeting that the absent fan may have a normal spending habit of £10-£15 (maybe more) in ground, the club have lost that aswell. So allround a plan that has potential to leave the stadium looking more empty behind the goal, losing potential revenue and more importantly, tainting the relationship with genuine fans, instead of tackling the cheats.
