As a rule of thumb we always allow an hour for travel to each park. We did not rent the golf carts and we were fine. We were in cabin #2427, it was a short walk to the internal bus. If you are going to Epcot/AK/HS catch the bus going in the direction of the Outpost Depot then transfer to the park bus there. If MK take the bus in the direction of Settlement Depot, then short walk to marina to the boat going to MK. The boat will also make stops at Wilderness Lodge. Take a look at the map here on this site and decide where you think would be the best location and request that loop. I was just looking at the map at the bus transportation and it says you travel the bus from the Settlement Depot, we stayed there May 2011 and it was not like that so you may want to ask when you check in. No matter what you will have a great time!
