Just FYI, I've encountered the smaller coffee pot in a studio a couple of times. All you have to do is call housekeeping and they will switch it out for a larger coffee pot. But normally there is a larger coffee maker in most of the rooms. I know the OKW studio we were in in August had a 12 cup.
I doubt we'll ever see the single serve coffee makers in the villas because the cost is so much higher for the coffee. We leave in 8 days, so I'll report back if anything has changed.
