The only problem is that the item said that SOME guests wouldn't be able to pull fastpasses. Who knows what that means exactly.
From all of the info I have gathered here on the boards... The FP- system is not connected to the FP+ system. The FP- system can be set to verify if whatever media goes into it was used for park entrance or not. When it is turned "off" so to speak, people can use the KTTW cards including old ones that never had tickets attached. It is my unconfirmed thought that if the system gets turned back "on" that people who have FP+ but also an AP or separate ticket like UCT that they may still be able to use that for FP-. What I have not seen confirmed is whether they need to enter the park with the AP or UCT ticket.
Will have live details in a few days and post then.
