Hi Herc,
When exiting VV property, you take a left onto International Drive until it ends which is 536. You take a right onto 536 and just follow the Disney signs. It seemed like it took the same time (10 - 15 min) to get to MK, MGM, and Epcot. We did not go straight to AK from VV so I can't tell you what the straight route is to that park from VV but I am sure they could at VV. I think you will really like this place.
