I'm am by no means a Disney expert and am pretty new to the boards, but in the past two years DH and I have stayed at both CSR and POFQ in mid- October. We both very much preferred POFQ, however, we do not have kids.
I really loved the small size of POFQ as compared to CSR. Though our building at POFQ was probably one of the farthest from the bus stop/main building (POFQ has only one bus stop area located right outside the main building) it was only a few minutes walk and we ended up taking a shortcut through a parking lot on most days.
I really liked that POFQ only had one bus stop, because that meant when we were picked up we got to go straight to the parks. CSR has four bus stops which, depending on which stop you use, meant waiting a while on the bus before actually heading to the parks.
I've read that POFQ often shares a bus with POR, however, when we were there in October 2012 this only happened to us on the way back to the resort from Epcot and HS. In those instances, the bus dropped off the POR guests first and then us. It is possible to get off at POR and walk to POFQ, though we didn't need to do that in that instance.
Clearly, busses are a big deal to me and I was a lot less stressed and irritated taking the buses at POFQ.
When we stayed at CSR we were near the main building as well as the main bus stop; however, this resort is so spread out it could make a trip to the main building a little less convenient than it would be at POFQ. I feel like our wait times at the resorts were similar, but overall I would say we waited less as POFQ; however, that could just be luck.
One thing I did find to be better at CSR was the main pool. We enjoyed the slide and theming. This may be more important to you since you are traveling with kids in July.
At both POFQ and CSR we only ate breakfast at the CS location in the main buildings. The CS location in CSR consists of several different stations with different types of food and you can go and choose what you like and it will be made for you as you wait. It is very spread out and I always ended up confused. It's kind of like a buffet though because you have a server who brings your drinks and you pay as you leave instead of up front.
I feel that the breakfast food at each of these locations is pretty much the same, it's just the set up that is different. At POFQ you also get your food at different stations, but then you pay and sit down and do not have a server to bring you drinks. I liked this better just for the fact that the food area was smaller and more contained, though the are pretty much interchangeable in my book.
I also think the rooms at these resorts are very comparable in size and comfort, though I felt like my room at CSR seemed older, though this is not true at all, so maybe I'm just remembering wrong. One thing we could get at CSR and not at POFQ was a king size bed.
We also got to take the boat back to POFQ from DD, which was nice.
Overall, DH and I really enjoyed our stay at both these resorts, but if I had to pick right now which to go back to I would definitely pick POFQ.
Regardless of what you choose, have a wonderful trip!
