Concerning last yr's FTP, I am 100% positive the UPH passes were free the three additional days.
The FTP was never, ever advertised here in NC so whe we were booking our trip, I first entered all the info into the WDW website and got a "price". Since I rather book on the phone than on the computer I called and that was the first time I heard about the FTP. So we went from staying 4 nights/5 day UPH for $ X.00 to staying 7 nights and 8 days of UPH for the exact same amount . We were so thrilled with the deal.
BTW we made our reservations in mid-June for our trip at the end of July and the FTP was still available for the dates we wanted.
