I’m not suggesting that the Club would want to advertise this facility up front, but if in the afternoon they have a few dozen uncollected tickets, why not put these on sale online?
The suggestion is that uncollected tickets be purchased online and then collected at the ticket collection point by those who have been successful. Hundreds queuing for a handful of uncollected tickets would indeed be a recipe for disaster.
I’m not sure that you even need that. The website buy button will presumably only be green for those eligible to purchase. Purchase on phone; receive email; present email at ticket collection point.
Have a cut off time for collections.
Make uncollected tickets available on line to pre-registered fans in Tiers 1 and 2.
Physical collection window open for say 15 or 30 minutes.
