The Inn rooms are basically studios. They are rectangular, more like at BWV and the like. They do have 2 queens where the true studios have a queen and pull out full. As for amenities otherwise, they are the same.
We've stayed twice in Inn Rooms and both were equipped with the microwave, refrigerator, coffee maker, etc. I've never stayed in a studio, but I assume they are pretty much the same. There are a few paper plates, bowls, spoons, etc... but I don't recall any "real" dishes. Hope this helps.
Here is the list of items at the VB Inn rooms(from DVC website)...
