I've see Scarefest (Sat 23rd) sold out well over a week in advance. Then a by mid week before the day, you can buy tickets again. I'm starting to assume that initial sell outs are base around staffing & trying balancing out the crowd numbers over the 2 weeks. Then increase numbers on certain days when they are confident they will have enough staff. I'm assuming they just don't have the staff to run the park at full capacity every day going by whats been said in past on here.
