Is it possible? I would think Disney frowns on this, thinking that the whole point of the free dining deal was to bring in NEW bookings, not adjust older, already established bookings. But I'm curious, are there people here who have done it, and/or do it all the time? I'm assuming even after booking the initial package online, that adding the free dining promotion would then have to be done over the phone? And if it's done over the phone later, does it show up on the online booking screens? Are you given a hard time by the reservation line when you call and ask?
