I agree with others to make Safari 1st, then Everest, then Kali (while you're in the Asia area). YOu get 2 hours with the free Kali river lockers, thouigh even with a FP you may be waiting in line for 30 min, so there goes some of that time.
Why are you trying to only do 1/2 day @ AK? We were there 5/6 and were there from opening to closing, there is so much to do, we wished it were open longer! The flight of wonder show is great and shady break, the trails are really worth it, especially the bird watching areas - beautiful birds will be only a few feet from you. My husband and son also liked Primeval Whorl coaster in Dino land> I just found AK so pretty and colorful and "different" than MK or that it was actually relaxing to be there. I hate idea of getting back to the mass of scooters and strollers and crowds that is MK in the afternoon- though it is much more tolerable at night. I would give AK more time. It really clears out after the parade, and you can walk onto almost anythng except EE, Kali and Safari.
