Hello! I have been a member of the DIS for a while, but have never really checked out the Codes and Rates boards, so please forgive me for asking... Can someone please explain how the Codes and Rates work? I've seen different threads started for different months, so I'm guessing that they are mostly different. We are going in September, and were able to take advantage of free dining since we booked before we checked out on our last trip. But, if there is a code for September, would I be able to take advantage of that as well? Thanks in advance!
