I just saw the same thing on the member web site. It really steams me that things like this can't be announced earlier. DVC knows we book our timeshares 11 months in advance. DVC resorts near Epcot fill up fast during F&W, so it would be impossible to switch reservations at this point. Had I known there was a special booking option for a specific PFTS, it would have influenced the dates we booked for our trip. It's too late to do anything about that now. So this becomes a perk only for the members who were already planning to be there on October 3rd.
Sorry, didn't mean to go off on a rant there. I'm generally confused by Disney's entire F&W philosophy. For an event that's grown so popular (and certainly makes them a great deal of money), I can't believe it's so poorly managed. Everything seems to be finalized at the very last second. Heck, they should already be making final arrangements for the 2016 festival, much less announcing things for the one that starts in a few months.
