I would go POFQ, I have had really bad luck at POR, they don't see to understand what is needed, even if you tell them. And it is very spread out if you have issues. My mom is blind and we requested preferred, before they had that catagory. They put us in the last manor, in the middle of the back. There are flowers, bushes, gardens, stairs, and hiding elevators, it was awful, we had to wait three days to be moved. We tried again two years later and the results were not much better.
At POFQ we requested what we wanted and why, a boy a week before we got there, sent a fax letter, and both times had the best room we could have asked for. No we were not the closest to the bus or food court, but then again that is not what I asked for, I assumed they would have though because mom was blind. They gave us the end room near the dock in building 2 once and the next one same room in building 5. We did not have to go thru gardens, or fences to get to the room. We had extra windows, so what little shadows mom can see she did. We were less than 3 minutes from food court, one minute from doc to dtd, and 5 minutes from bus, and one minute from pool. For the first and only time ever, we got Braille instructions in our room, for the phone and for the safe and for evacuation. We have stayed DL and WDW every year for 20 more years and have stayed at three Disney resorts since then and this is the only resort to ever give Braille information, and we gave us asking for it 20 years ago, so we did not even ask. When we went to the front desk for anything during our stay they ask if the room was working out for us or if we needed to change. The second day we complained just a little about the bus, not that it was not good, but twice the bus drivers did not let my mom on with the w/c people, and the had a hard time with the squeezing of the people ( when blind this can be very scary), the front desk people called and fo the next week my mom was allowed on the bus first and got her seat every time, and also the bus drivers mad a point to make sure she was sitting on the way back, (I know we rhode is tired but a blind women has a hard time on a crowded bus when standing).
I am sure there are other resorts that are great and we just have not checked them off our bucket list yet, but POFQ went way above any other resort we have ever stayed at. F I were you, I would ask for a standard veiw, at POFQ they are all nice views and I would asked for the back side of building 3 or 4, yes you will be near the parking lot, but that gets you close to the bus stops and really close to the food court, which would be slightly closer to building 4. There is a map on touring plans if you want to request very specific, and this is one hotel that will allow very specific.
The other reason I would go POFQ, if you have to share buses, POFQ is first picked up and first dropped off, so you are more likely in am to get a seat on the bus with the little ones. Sometime POR and POFQ share the buses, so you want to be first on. Also there is only one bus stop at POFQ, and 4 at POR and there is no way to say who will get picked up first, POFQ and outer buildings of POR or POFQ and main building of POR. And you may have to wait several buses if full and if grandpa needs a w/c and there are already two on bus you have to wait even if bus is empty.
Have a great time.
