DVC members get discounts at specific restaurants (and in most cases, only specific times of day). Looking through the list and relying on my memory of which restaurants do and do not have character meals, there don't appear to be any.
There is a DVC discount at Cape May Cafe, but that's only valid in the evening, and their character meals are for breakfast.
If it's practical for you, the best thing would be to get an AP and then order the DDE card and you would get 20% all food and drinks (including alcahol).
If you already have an AP it's a no brainer.
Unfortuantely it is not practical to get an AP. I don't have a problem paying full price for the character meal, I just wanted to double check to make sure we did not get a discount. No point paying full price when you don't have to!
