My experience - first trip to POFQ we requested a room in Building 4 or 5. We arrived late (because of flight delays) and we were stuck in one of the farthest rooms in the resort. (Building 7, 3rd floor, far end of the building, the LAST room out.) We were told because of our late arrival that was all that was available. Because we had DD3 at the time, we did not want to have to trudge that far each morning for breakfast or later for the pool. The next day we requested a move, and they moved us over to Building 2.
Second trip, requested building 4 or 5, got building 5, but again 3rd floor, but overall nothing to complain about.
Third trip to POFQ, I was having foot problems (heel spur) and had requested Building 4 or 5 again. (This was not a lie, I was in serious pain just a few weeks before our trip. I had cortisone shots and treatments leading up to it, and by the time we got there it was pretty bearable. But, I would never lie about this to get a good room.) I called again the day before we were to arrive, as well as the morning of, to the hotels direct number. (Still programmed in my cell phone.) I described my issue, and asked them to please see what they could do. (Again, wasn't trying to be picky, just a central building.) The last call, they told me that they had my room request and would try to accomodate. Well, we arrived late in the evening again (about 8 PM), and got our room. We were given a GREAT location. Building 5, 1st floor, literally about 35 feet from the entrance to the food court on the corner of Building 5, about 100 feet to the pool, and not far to the bus stop either. I couldn't stop commenting to DW the whole week about our great room location. I still imagine we will never have it that good again.
So, my advice would be, make the request on your ressie, then check that the request is there some other time leading up to your stay. If you arriving early in the day, you should have no issue. If you arrive late in the day, call the resort that morning, and try to confirm your accomidation.
