The last time my daughter was at Disney (2005) we did not pay for any buffets for her. We did not do any entertainment dinners (ie hoop de doo), but would have expected to pay for her there. We went to Crystal Palace, Chef Mickeys, Ohana....
She is clearly disabled, and cannot even have a taste of food. I do hope we won't be paying for her buffets this trip, we have a couple planned.
