I stayed at both, most recently at the CBR. I loved the CBR in that it was part of what became our best Disney vacation. The POR is no slouch and that still my favorite because it feels so much more lower key. Depending on the building for the CBR, transportation is a breeze. I think we were at the Jamaica building which happened to be the very first bus stop. That was a plus because that guaranteed out ability to get on the bus without waiting for the next one.
If I were to choose between the two, I'd select POR, but talking with my family, CBR wins out because they liked the pool better, the restaurants and overall the look and feel
