We were in a POR AB room in March and we loved it. Yes it was a shared walkway, but DW and I were able to sit outside after the kids went to bed. We were in AB 27. This put us beside the "river", close to the main pool, close to a quiet pool and very close to the main building. The view outside our room was excellent, particularly in the morning!
If you only plan to sleep and run,,, don't spend the extra $$$... BUT if you enjoy lounging and checking out the scenery... it's worth it.
