We have stayed at both and like POFQ better. CS is nice, just very spread out and can be a walk to/from the bus depending on where your room is.
POFQ is much smaller and more compact. Everything is close (food court, pool, bus stop) and has only 1000 rooms compared to others which have 2000-3000. Makes a big different getting in and out of the foodcourt, etc. It is also nice being on the river. THe pool is nice and if you have kids, they will love the serpent tongue slide .. Can also take a leisurely (yes, LEISURELY) ride to downtown disney (if you are on a time schedule, take the bus). You can also walk to POR on a bike path, rent bikes, paddle boats and surrey bikes if you like. We like POFQ the best and are staying there again in Dec. We find we keep going back to it ...
