Class action won't go anywhere. You pretty much sign off on being at the will of Disney when you even buy any sort of ticket. Same with concerts, sporting events, etc. Read the fine print on your ticket.
"Passes do not guarantee theme park admission, especially during high attendance periods. Admission to the theme parks and availability of standard theme park parking are subject to capacity and other closures. Other restrictions apply."
As much as AP holders are keeping the business afloat, they're not going to turn off the vacationers who are going. I understand the frustration but from someone who is not local and can only go once a year and spends a high amount of money to do so, it's not really fair that I have to tell my young children the line is too long for a ride so Johnny 40 yr old can go on the same ride for the 8th time this month.
