For MK access, I think that CR has the best location. You can walk (5 -10 min) down the brick sidewalk, take a boat or take the monorail. On the way from the MK, the CR is the first stop. Going to MK in the AM since CR is first, you don't have a problem finding a seat. To get to Epcot you take the monorail to the TTC, then change to the Epcot monorail.
