Sorry,but I was not happy with CBR when I went a few years ago. I had stayed at the WL, POly and Coronado in the past,so maybe I was a little spoiled. The CBR seemed a little dated and the I really didn't like the food court. The Coronado was so much better.
I have never been to the POR so I can't compare. Just one point of view though and I see that many people do like it.
