Depends how viable a multi story car park would be to save on space by building upwards. If the offers are good enough you might get some Saturday afternoon away fans who don't go home until Sunday morning. On a matchday it would do great trade even of those who aren't off to the match. A family can meet up for dinner. Some go to the game and others go shopping around tarn before meeting back there at 5 o clock.
Instead of doing a fanzone they could have just improved the bars in the East and Ponty, the West is beyond repair.
