Yes.
Bus between AK and Epcot in both directions.
Also, although you didn't ask:
Bus between AK and DHS in both directions.
Bus between Epcot's front entrance and DHS in both directions.
Boat between Epcot's International Gateway and DHS in both directions.
Bus between AK and the TTC in both directions (then monorail or ferry to MK).
Bus between DHS and the TTC in both directions (then monorail or ferry to MK).
Monorail between Epcot and the TTC in both directions (then monorail or ferry to MK).
I think that's everything. Oh - no transportation between the theme parks and Downtown Disney, or between the theme parks and the water parks
except that buses going to AK also stop at Blizzard Beach.
Okay, THAT'S everything
