It is a tough choice. I, like some of the other posters, have stayed at both. Each has it's own unique qualities that make it wonderful. If you are looking for a really nice place to stay but money is a factor, than I would say POR. It is a good bit cheaper and still very beautiful. However, if money is no matter, than I would way out each.
At POR, you will have more walking to do. Depending on which building you end up in, you may either have a hike to the food court or the large pool - this is the one with a slide that kids love. You could even end up with a bit of a walk to the buses. The good thing...they keep the grounds very well kept up and the walk is always beautiful. A huge plus with staying at POR is that the kids can even go play at the large POFQ pool. Also, the food court is very nice with a sit down restaurant as well. The rooms are very pretty with plenty of space for a family of four. Lots of activities to do here!
At WL, there is no food court but plenty of places to sit and eat or even grab something and go - we love to take stuff out by the pool. The pool is very picturesque and has a very nice slide for the kids (and adults)! Getting around WL is a little easier since things are all contained more in one place. The rooms are very gorgeous and quite large. To give yourself a little more space, you can even ask for a bunk bed, plus, the kids usually love this! We always enjoyed getting a bike and riding over to Fort Wilderness and the boat ride to the Magic Kingdom is wonderful.
I really couldn't help you on which resort to choose. Each have their own special qualities that make them magical. You just have to write out the pros and cons to each as far as how they fit your families needs and decide from there. Either one you choose, you can't go wrong with! They both help make you time at Disney very magical!
