From my personal experience, I am good with any room there, since its a smaller resort, all rooms are good location. Buildings 5 & 2 are down more by the water/pool and 4 & 3 are closer to the lobby/bus area, so those are the 4 best buildings I'd say depending on what end you want to be situated. The other 3 buildings are more to the side of those, but again all are pretty good I‘d say due to the layout and size of the resort.
POFQ is one of my top favorites out of all resorts in Disney!
