AK and MGM dovetail nicely I think. I would do AK in the morning, making sure I covered the Safari, Expedition Everest, Dinosaur, Flights of Wonder, It's Tough to be a bug, and lion king. If I had time, I would also do primeval whirl (not worth a long wait). Then hop to MGM and get FP for RNR first thing (before they run out). You should be able to do most of MGM as well before it closes.
MK should be open very late this time of year, so you could do MGM in the morning and then hop to MK (but then you would miss fantasmic).
