I can't really predict whether you will like POR if you are accustomed to the Poly. It's hard to beat the Poly for convenience and atmosphere, but remember that you would be paying quite a bit less to stay at POR.
I can say that, for our family, even though we could probably afford to stay at deluxes for our trips, we find POFQ and POR to be a better value for us; we don't spend that much time at the resort itself, and the wonderful amenities at PO, as well as the great pools seem to put them several steps ahead of the AllStars.
The proximity to DD and the boat transportation there is a major plus for us. We enjoy going to PI once in a while, and we always make the trip to DD a couple of times to eat and shop, as well as to do DQ. The boat ride is beautiful and relaxing at the end of a long day in the parks, and the DD area always seem much more "happening" than any of the resorts we've stayed at (we're night owls, and even the BW goes to bed much too early for us!)
I've seen plenty of postings from people who just can't seem to enjoy a less-expensive resort after staying in a Deluxe, and I guess I can understand their points of view. I guess it just depends on what your expectations are. I think POR and POFQ are beautiful; they are our favorite resorts to stay at, and I think you'll enjoy them too!
