In Sept 06 we stayed at Pop. Last month, we stayed at POFQ. When we book our next trip, it will be at POFQ. Pop was LOUD. It was sensory overload for my dd. While she liked looking at everything, it was over the top. Also, our room at Pop was in the 80's section facing the parking lot and took forever to get to Classic Hall. When we returned from that parks at night, it was a long walk holding a very sleepy dd.
As for POFQ, we LOVED it. It was peaceful. The pool was great for the kids. Now, this past trip, it was only me and dh, but our kids would have loved it there. Everything was clean and the grounds were so beautiful.
Now, Pop does have a larger food court and shopping area. For us, it will be worth the extra money to stay at POFQ. Oh, and when you get to the parks using the bus system, the Pop drop off is always the furtherest away. I guess since it was the last resort built, it get the last bus depot.
It's a matter of what will work best for you. We found our rooms at Pop to be loud. We could hear neighbors, at POFQ, we could not. When we returned to POFQ from the parks, we felt relaxed immediately. At Pop, it too much to relax. Good luck with your choice!!
