WRT POR/POFQ remember the distance between the north end of POFQ to POR is about the same as the distance to the POFQ's lobby. Obviously the distance to POR's lobby is longer, but it's an easy stroll, or you can just take the boat.
Of the two, I personally much prefer FQ as if busses are being shared between the resorts, FQ is the first pick-up and first drop-off. I have been known to wander over to Riverside to sit in the shade in the afternoon though. I find French Quarter most pleasant during mornings and evenings. Riverside for me is at its best during the day.
