I know that in 2003 they weren't accepting any discounts for the Candlelight Processional packages. Usually they start taking PS for those at Disney Dining about 90 days out, just like any of the other dining, however, since they basically have to book both the dining and make sure it matches the times for the shows, it may take a bit longer than the normal dining PS. Also, you will have to give a CC number, and it will be charged to your card. If, for whatever reason it is not paid for and you go to pick up your tickets, the tickets will still be there, but you will need to pay for for the package then.
