I'm curious about this, as well. I did add the dining plan to our reservation. If FD is not offered, I plan to remove the dining plan. If FD is offered for our trip dates, I likely will book a new reservation and cancel the existing, as my understanding is that it's better to get online right away on the first day of the FD offer (so, not waiting for Disney phone lines to open to simply try to apply the offer to existing reservation). Does anyone know what will happen to my existing dining reservations, specifically the ones that requiring pre-payment for which we reserved using the dining plan credits, rather than actually prepaying? I hope I'm being clear in phrasing this question, as it's starting to confuse me.
