I'm not sure this will help, but when I went to Mousesavers.com and found the new codes for FL residents it gave me the option of booking over the phone or online at Disneyworld.com on the FL resident part. The link took me directly there because once I entered my dates and resort I wanted the page with pricing showed it to be FL resident rates. I didn't see where I should put a code once I booked. I checked regular rack rates for the rooms and saw the difference. So I figure....at least for FL residents, the code is already applied when booking. Maybe you can do the same? Go to Mousesavers and look at discounts for general public or whatever you need and see if the Disneyworld link gives you discounted rate once you price your rooms.
