POR without a shadow of a doubt. It is a beautiful resort, fairly recently refurbished, beautiful buildings, good amenities, pool, food court. Just a nice place to be. Ask for a room in the mansions section, it is quiet and relaxed.
POFQ I have only seen from the outside. Seemed a lot more cramped and a lot more manic than POR.
CBR just seems a bit run down to me. Rooms and theming are good and the beach is a bonus, it just doesn't appeal to me though.
