It doesn'et really matter. It might save you a few minutes on the phone when you call to have the FD coded added to your reservation, but if you are planning on calling first thing, when the codes come out, it's not going to matter if you make your resort reservation now or wait until then. The important thing is to make sure you have all of or Advance Dining Reservations made already. If you are going in October, your ADR window has been open for at least 2 1/2 months. All of the popular character meals and restaurants may already have limited availability, and will most certainly fill up when FD is released for the general public next week. You don't have to have resort reservations to make ADRs, so I would be concentrating on that now, if you have not done so already.
