From POFQ, you can also take a boat to DTD. Disney Quest is closer to the West Side than Marketplace, but the walk from one to the other is not far at all.
You could also go to DTD and take a Boardwalk, Beach Club, Yacht Club, Swan or Dolphin bus to the resort to get to Beaches and Cream. I am assuming that you will be going mid-day so the busses would not be terribly full.
Just another set of options to think of...
