I have stayed at all of the moderate resorts, and I like the POFQ the best. I really like the atmosphere. I also love the compact size of the resort. Even the furtherest room from the bus stop/food court is an easy walk. The pool is really cool, as well. And the boat to Downtown Disney is nice and relaxing.
The two main things that the POFQ does not have that the other moderates do have are quiet pools and a sit down restaurant. These don't make a difference to me, but I know they do to some people.
I've stayed at the CBR twice, and although it's a very nice and beautiful resort, it is much too big for my tastes. The first time, our room in Trinidad South was about a 15 minute walk from the main building. If I were to stay there again, I would probably spend the money to get a preferred room.
I stayed at the CSR when it first opened, and I didn't really like it. It is a beautiful resort, and the rooms were fine, but there were a few things about it that really bugged me. The walls at the CSR seemed very thin--we could hear footsteps of the people above us (and they weren't stomping--just heavy walking), and we could hear the TV and voices of the people around us. At the other moderates, I never heard a peep from our neighbors. I find that at most of the newer resorts I've stayed in, the walls seem thinner. I also do not like the way they run the food court at the CSR. A host or hostess seats you, and they will get your drinks for you. You go, and get your own food (which is served on real plates instead of paper). When you are done, the host or hostess will clear the table. For this service, you an additional 10% is added on to your bill. That can add up at breakfast for a family every day.
I think for this trip, you might want to stay at the POFQ just because you know that the rooms are all freshly renovated. The rooms were completely gutted--the wallpaper, carpets, and furnishings were all replaced. It will be like staying at a brand spanking new resort.
No matter which one you choose, I'm sure you'll have a wonderful time! I don't think you'll be disappointed in any of them. Have a great trip!
