As a Brighton fan I echo this. We don't have any pubs at the Amex, so many fans arrive at the stadium bar at 1pm and stay until 6.30pm. Eases congestion hugely and like you said, spins a pretty penny for the club. In fact, my dad and I tempered how often we went to the Amex a few seasons back due to how much you end up spending enjoying yourself on a matchday! Alternatively, many people still go to Brighton or Lewes to drink beforehand and then get public transport to the ground, so this could still be done in Coventry, Kenilworth and Leamington.
I studied/lived/worked at Warwick Uni for 8 years until 2018 and thus have a big soft spot for the Sky Blues. I almost stalled the car when I heard this announcement when listening to the Price of Football podcast on the way home from work. I understand that you would all be at the very least cautious in your optimism due to recent years, but I am beyond excited for you guys if this goes through. I'd slightly mourn the loss of more green space at the University as when I joined in 2010 it had a lot more than it does now - however, at least this time it would be for a more than worthy cause!
All the best. #PUSB
