I put in a call to our family's TA. As we have already booked our trip, in order for us to take advantage of the
free dining plan, we would have to cancel the land portion of our trip (the hotel where we requested a preferred room, myw tickets with the park hopper option, and dme) and we would have to rebook. We would have to rebook with a standard room. I was told there were only a limited number of preferred rooms. Anyway, it would end up costiing as $112 plus about another $70, since we would be paying the rack rate.
Oh well. I'm not upset about it, so no worries here.
