AKL -> Studios - 8 mins
AKL -> MK - 13 mins

(Depending on route... add 2 mins per resort...)

Routes can vary. Add for the following:
CR/Po - Add 4 for CR
CR/Po/GF - Add 7 for CR, 4 for Poly
WL/GF - Add 5 for WL
WL/Outpost - Add 5 for WL
WL/Settlement - Add 3 for WL
FW alone - Add none

If you start compairing times, you can see that AKL is no worse off than other resort areas, and it's actually better than alot of them. The longest time for AKL is to the MK area, and that would be expected because of it's location. But if you study some of the other Epcot resort times, you will see that to the MK, they too have times that are within 2 min of AKLs times. Add this to the factor that AKL doesn't share it's routes with the exception of the water parks, and you can see that AKL is not at any significant dissadvantage than any other resort.
Yes, if MK is the only resort you are going to visit, then it is the longest ride (at 13 min), but if you are visiting all the parks on your stay, then the 5, 8, and 9 min rides are not really an issue seeing that other resorts (Caribbean Beach MK - 11, Epcot - 7, Studios - 5, DAK - 7) are only off by 2 or 3 min, and CB is centrally based versus AKLs location.
Like BRER STITCH and lebernadin said, the extra min should not be the most worrying thing on your vacation.
Have fun!
