Yes you can still do it,obviously Disney will have to make the offer first! I've read a couple of threads on the US discussion about the possibility that Disney will not be making the offer but instead it will only be available to those that were given a "pin no." on their last stay. We had all the leaflets in our room last year but didn't pay too much attention as we knew that we wouldn't be going this year

As Wayne says I would crunch the No.s to see if the US Free Dining will be cheaper.
