Keep in mind, when it is said they cut them loose it does not mean they are physically separating one park from the chain. They just are not funding them as much as they have been, if at all. The park actually puts a lot of money in savings, so I imagine that they could dip into that to try and equalize prices so that they can slowly raise prices instead of a huge price hike out of nowhere.
As far as EZPay is concerned, they still have to keep their contracts unless the product is not offered any longer or they have some escape clause, meaning they will more than likely continue to do EZPay. It is steady money rolling in as opposed to the fluctuating profits of single day admission tickets.
I see no immediate reason to cut our heads off and run around. Let's not blow this situation out of proportion.
