Today Disney effectively used the FD carrot to wrestle even more money from me! Originally we had a preferred room at POR for 5 people (way before any FD announcement, didn't think thanksgiving would be included). A POR room for 5 with FD wasn't available for our dates on 8/1, our #2 choice (AoA) was not on the list, my #3 choice (Poly) was unavailable - but we decided to "splurge" and go with the Contemporary (Garden Wing) with FD for only $7 more than our original POR stay with no FD. After endlessly checking both the Poly and POR for availability, today a standard Poly room with FD finally became available, so I switched to that. It was another $150 or so, but the kids really wanted AoA or Poly if we weren't going to keep our POR reservation.
They'll be happy, but I'm still going to secretly keep scoping out POR, hoping a room for 5 becomes available.
