what's funny about this is MK is the easiest one for me to figure out! the rest aren't terribly difficult but it's inevitable that there will be some criss-crossing on those, at least in my mind.
here's my plan of attack for MK
~swing by space mountain to get a fastpass.
~fantasyland first thing (peter pan and dumbo first since those are always the longest lines)
~go back to tomorrowland and do that/use FPs to space
~take secret pathway beside space to toontown and conquer that area
~take the train to frontierland
~get FPs to either splash or BTMRR, depending on which one has the longer wait, and ride the other one
~go to liberty square and do that area
~take a shortcut through where the bathrooms are to get to adventureland and do that area.
that's usually how we do things and how i advise clients to do it, as well.
