I've stayed at POR, POFQ, and CBR, and I would have to say that my favorite is POR.
I also did not care for CBR - I wasn't too impressed with the theming, felt that it was too spread out, and the bus service is the worst that I've experienced at any resort (although, to be fair, it was probably just luck of the draw!).
I really loved POFQ and would happily stay there again! I loved how quaint it was, the size of the resort, and the beautiful, themed grounds. However, I thought the interior of the rooms at POR looked nicer (we stayed in the Mansions) and the food court was considerably better, with more options. Although POFQ does have beignets...
In terms of size, I did feel like POR was less spread out than CBR. I went with my mom who is in her mid-sixties and neither of us had any trouble with the walk to the food court, front desk, etc. However, if someone in your party has mobility issues, it can't hurt to reserve a preferred room if it is a high priority.
