This is just a theory (wild guess), maybe they will release a general free dining code for the last part of the year but they are waiting to do so until after July 26. This is the day that dining packages go on sale for the candellight processional. This way it gives priority to people who dont have the FD package to reserve first. I know that you can make the ADR and tehn get the package but I guess there are people that dont know that.
