Hi Margaret!
There are a couple of special offers which cover the January time frame. To read more about the current offerings, be sure to visit the
Special Offers page of the Disney website.
Looking at that page, I do see the Free Dining offer is available in January, but does have specific arrival dates, which do not coincide with your arrival:
2011: Jan 1 - 5 • Jan 9 - 13
If you are flexible, or see another offer that you are interested in and would like to apply to your reservation, give your travel agent a call and see if they can help you take advantage of it. Disney often allows modifications to existing reservations when a special promotion can be applied. The travel agent you are using should be able to find out if it will work for you.
Hope this helps, and that you can get a great deal!
