I have a cunning plan.
What about the disabled section ?
We pave all around the outside of the arena and mark the 3000 seats placements 2m apart around the outside of the IAW.
We add titantron (enormous screens) around the outside wall of the arena.
We then add inside multiple cameras showing the view from each block which on the titantron would merge with each other to show your normal view of the game.
We then hire the space outside on the pavement where we usually sit, take our lounger, deckchair, armchair, whatever and watch the game going on inside outside.
If raining the shop can sell clear umbrellas so game can still be seen.
Mobile beer. Snack, pop sellers can wander around to serve supporters at their seats.
Outdoor portable toilets with queuing system or instead of bringing a chair bring a commode, never miss a single play.
There, problem solved. You can thank me later Devil's Org.
