I think, with some organisation, it wouldn’t take too much to get ‘crowds’ into Home Park.
Masks encouraged (but not compulsory)
Hand sanitizer dispensers abundantly available.
Every other row empty.
Every other seat in the occupied rows empty.
Tickets sold only online (ST holders first).
Members can link accounts to get tickets ‘together’ (still alternate seats).
Tickets sold ONLY IN BLOCKS, not specific seats.
Turnstile operators behind screens.
Specific turnstiles for each block, concourse taped off, one way system, no outlets open.
Rows filled from one end only.
Tickets (with block no. clearly marked) checked by steward at block.
Blocks filled by row from the bottom up AND the top down (your choice) ONLY (not in the middle) every other seat must be filled in the occupied rows.
As each row gets near full the stewards ask for group numbers to fill the row (as happens at theme park rides)
Exit would be by row from the front, directed by stewards, everybody stays in their seat until the row in front is empty.
Leave the same way you came in.
Toilets would be the biggest problem but with no concessions open and only around 25% capacity, toilet use would be well down.
The best way would be to exit/enter the block in the same direction it was filled but using the empty row in front of yours. Climbing over shouldn’t be a problem for most people but I accept it could be for some.
The number of people in the toilets at any time and subsequent queueing could be organised in the same way as happens now with shops.
This is all really with the horseshoe in mind, I don’t know the interior layout in the grandstand and how different it would need to be there.
And that’s about it - simples!
This is all a lot of faff - necessary, but still faff - but if publicised clearly beforehand and directed and stewarded properly, it would only take one game for people to get to grips with it.
It would probably need a small army of new people to steward this, not necessarily the current ‘security’ stewards but it’s really not rocket science.
Not ideal by any stretch but better for everyone than the stadium being totally empty.
