We stayed at FW in August 2012. Because I knew I'd be eating at least 4 meals at our resort during our stay I asked lots of questions of Special Diets. They had a chef contact me and we went over options and were ready for us when we arrived. We had great experiences at TE and HDDR.
Our list of known allergies/intolerance at the time were (sigh, the lists have gotten longer since then):
DD14: gluten, milk, eggs, citrus (citric acid is ok), yeast, msg, peanuts (minor - cross contamination not a concern)
DD11: milk, hazelnuts, brazil nuts, citrus (citric acid is ok), peanuts (minor - cross contamination not a concern), sesame, blueberry, cranberry, raw carrots, raw fruit skins besides grapes, lima beans, hops, soy products other than Tofutti and Follow Your Heart (soys not the problem but we havent identified what ingredient in Silk and other soy products cause Oral Allergy Syndrome)
Me: gluten, milk, peanuts (minor - cross contamination not a concern)
Here are my TE dining reviews from that trip. We didn't eat at the dinner buffet but anything we got at HDDR could be requested at TE for dinner (like all buffets, the chef will prepare things in the kitchen to meet your needs and since TE and HDDR share an allergy kitchen they should be able to get you anything that's available at HDDR) so I'm including that review as well.

You know, looking over my reviews, I'm thinking that now that I've had to give up pork my options sure do look a lot more limited. That stinks. TE really did have the BEST bacon plus their pulled pork was amazing (we had it at breakfast but I would think it's available at dinner).
I don't know if all of this would be safe with soy allergies. None of us has to avoid soy. Most was pretty simple foods that I would think would be soy free but obviously you'd have to check (sauces I would think to be the most likely thing to contain soy).
