Oh what a great idea! I never would have thought of doing this, but now you have me thinking...
You have received a couple of great suggestions already. It makes a lot of sense to plan to cut down on travel. If I was going to do this, I would be sample resort restaurants on the monorail loop. You wouldn't need your car then. How about appetizers and/or salads at the CG, then a main course at the GF (Narcoosee's or Citrico's) and dessert at Kona in the Poly? Of course you could flip these three around in any order; they all have great food!
Please let us know what you decide to do, and how your experience goes.
