Emailed Disney about this one and got an unhelpful answer; they told me to refresh my resort booking and directed me to their web help desk . I don't plan on calling it as we seem to be getting everything we want, booking day by day, as we are not on the dining plan its not crucial. However I have informed them that the problem is wider than just my reservation and is being debated on Disney web forums!! I also thought that as I haven't linked park tickets to the reservation that could be a reason for it not working, but I disproved my own theory by not being able to book a resort resturaunt in the +10 window. Hope everyone gets their first choices when they come to book.
