Depending on where you are at the Boardwalk, you may or may not be closer to HollyWood Studios, some of the DVC rooms on the Kanal side exit almost directly to the walking path.
Regardless though, once the finally start with the Star Wars Hotel, then the closest hotel for Hollywood Studios access would be that one.
With all the Crowds we are expecting at Hollywood Studios due to Star Wars, makes me really wonder how many days
DisneyLand will be reaching Capacity once Star Wars Land opens up in that park. Its happend a couple of times without Star Wars Land, if the hype is that massive, I can see why Disney has taken such drastic measures, to increase APs over their and reduce crowds.
