We haven't stayed at CBR so I can't compare to there but we have stayed at POFQ and PORiverside. The first five trips or so were without our son. Just by chance we picked POFQ on our first trip. It was a new resort and we both really liked Jazz and thought we would like the sanitized version of New Orleans. We were right.
POFQ is much smaller than Riverside but you can use all the facilities at Riverside since they are "sister" resorts. That makes it nice. Both resorts sit on the Sassgoula (sp?) River and there is a very nice walking path between the two. We always enjoyed holding hands, watching the ducks and walking the river path. Was pretty romantic at night. We also like the cobblestone streets and horses along the paths at FQ. Plus, the fountains and courtyards spread throughout the resort are very nice. The other thing we liked was that since there are less rooms it appears to be less crowded when you are on the grounds. That is just my opinion but we've always felt this way.
The food court has just been redone and from what we hear it is similar to Riverside and that is a plus that wasn't there before. FQ is also the first bus stop on the route - when you get on and when you get off. For the most part, except when it is packed, usually first thing in the morning, the bus continues over to Riverside.
Overall I would pick FQ but I have heard that CBR is also very romantic and has just been renovated. Whichever one you decide, you will experience the magic, I'm sure. You might want to do a search on the FQ. That would give lots more information on the facilities and everyone's opinions.
