We have stayed three times at POR in the AB section and really loved it. I would say the Pros are: Beautiful landscaping and theme, several pools, the boat to DTD is a must, food court with lots of variety - something for everyone.
I would say the Cons are: Depending on what building you are in, you could have a very long walk to the Food Court/Lobby/Main Dock. Also, the buses were no joy for us -- LOTS of stops at the different stops all the way around the resort and many times they share with POFQ so stops there as well, so not ideal transportation in my mind.
