All tickets work in the fast pass machines- a/p's and less then 3 day park hoppers included! No one is excluded from fast pass. There are people that dont understand it or choose not to use it, but its not because it's not available them.
AAA was offering "enhanced" fast pass to guests staying onsite. With enhanced you could hold one fast pass for each ride that offered FP, at one time. You could not get a 2nd FP for the same ride until the 2 hour window or the return time came up- which ever was first. However, as of the new year, AAA is no longer offering that perk. But, the regular fast pass good for one ride at a time until 2 hours or the return time, is still in place for ALL park guests.
If you look on the park maps it will tell you a little about it as well.
