I got the Friday tickets i applied for a while ago now and my surname is later in the alphabet so not convinced by the surname order theory.
I have attended recent opens, and the last 2 at st andrews, but not sure if they prioritised regular attenders for these tickets or not.
Am sure that everyone who wants to go will get to go, it will just take time to process all the offers that werent accepted and redistribute them to those who werent lucky initially. Good luck everyone.
