I don’t know about international flights, but if you are taking ME back to the airport, you will leave disney about 3 hours before flight time on a domestic flight. Can any give the details for ME with international flights?
I’m only speaking for me, but I would not be wanting to spend hours on disney transportation my last day at disney. If you are staying at OKW and say you eat at Chef Mickeys. You have to take a bus to MK and then walk or take monorail to Chef Mickey. After the meal, get back to a park and then a bus to AK to eat at rain forest. After eating, taking a bus back to OKW. If everything worked great, it would still take a few hours of travel time. What if you got into one of those " I waited 25 min for a bus to turn up" things?
I don’t know how valid this site is, but it gives you some idea of travel times.

I don’t want to dash your plans, but just remember if you go with a running around plan and do run late, you can always grab a cab to get back to your hotel. Sure it will cost, but better than freaking out about missing ME and your flight.
[I]Just rereading my post, since you are at a hotel for the breakfast, you can get a bus right to AK. You don’t need to to back to a park and then a bus to AK. Still running around but one less step.[/I]
