I could see them offering a revenue based loyalty program, i.e., the more you spend the more perks you receive. That would put big spending tourists on a more even footing with local AP holders. It might not seem so now, but as Disney continues to increase prices they may come to the point where they will need to offer more perks to guests in order to make the high prices seem justified.
Such as recently getting to see movie previews
like Guardians of the Galaxy (this was our 5th movie preview so far within a year) & WAY better AP discounts than usual !!!
THIS is why I mostly pointed out the other PERKS we have been enjoying recently as DVC members. (Finally upgraded to Premier w/DVC discount - been asking for this for a few years now)
It may change if they keep offering great discounts for the AP's!
