You are best to call them. Codes are very resort and system specific and tied to your membership account in II. Or if you are not yet a member but own a resort, they will get a list of owners from the resort and send out postcards trying to drum up members with codes. In other words, one person's code is not likely to work unless they own the same resort or received the exact same offer. II will be able to tell you on the phone if you are eligible for a promo.
