We were at WDW Dec 13 - 20 2014. ASMu food court was not scheduled to be up and running from refurb until the 20th. It was already going when we checked in. Also HH was at tail end of rehab that was due to open Dec 20th. It was open on the 13th as well and every other time we were at MK that week. Good luck! I would think they put out the worst case date and shoot for before that to keep the crowds happy
