Looks like the club have tried to help it sell out:

Off track a little but I had to visit the North Stand offices yesterday and in reception area were various senior Sussex Police people. Presumably to discuss the policing of the upcoming Palace game? Might not be but it isn't that long really.
Most people I know that missed it just didn't want the hassle of the queues and police cordons etc on a weekday night. It just adds grief for a lot of people that are trying to get home and are weary after a day at work.
Personally I went to both league and cup game plus I took my 7 year...
Yeah and a season ticket guest ticket is always in the season ticket holder's name but an additional ticket (ie the season ticket holder has 2 tickets in their name).
