All tickets except Annual Passes (and I THINK the Florida Res Discovery Disney ticket but I could be wrong about that) can be converted to the RFID media... In fact, if you come in to guest relations with a simple ticket question, they're supposed to switch your tickets over even if that's not what you came in for. This is for all day guests -- not restricted to just Disney resort guests.
And it is now at all the parks and DTD as of yesterday.
