Of those listed, I've only stayed at POR & almost at POFQ (they moved us to POR, but we swam there) All Disney pools are geared for kids, but I found the whimsical dragon style of POFQ seemed to draw more little ones. Please understand, I love kids, but 25 screaming (mostly happy) 2-6 yos was not my idea of a relaxing Adult atmosphere. POR's Old Man island seemed much quieter and even the hot tub felt secluded.
That, plus the night entertainment, I vote POR.
