Codes etc for that time in November generally come out around August. You can more than likely count on some AP rates, and maybe even some public rates/package discounts, but it will be awhile before they are released. As for pin codes that are out right now (which are given to individuals, usually by email, and can't be shared) are good through October, I think. It's always worth calling central reservations just to check and see if you have one though.
