A few other thoughts...
Of all the pools the one at the BWK is deepr than pretty much all the rest. Most are not vey deep.
Forgot to say, the Swan/Dolphin have very nice pools. they share pools, but there are - I think - 3 of them: a large grotto, a lap pool, and one that is more basic shape but w/volleyball.
Speaking of shared pools- if you choose POR or POFQ you can use both pools, but it s little bit of a hike (especially when you're wet.) In cooler months, I prefer the hotels that hug their pools, like AKL and WL. Those pools are sheltered. Almost any time of year, the top of the YC/BC pool slide can be breezy and chilly, and STILL there's a line of folks waiting to use it.
A bonus of the YC/BC pool is the sand bottom sand play area, and bonus kiddie slide.
GF, AKL -Kidani, and CSR all have fun bonus water features. BWK kid pool is very dull, but some of the values have fun splash areas for the very young.
It kind of depends what you want in a pool.
Also, well, some of the feature pools can be quite loud during pool activities. One of my favorite quiet pools is the one at CR. It overlooks the lake, and we often have it to ourselves when we go there. the BWK quiet pool is also better than most, as it has pretty gardens.
Still one more option to consider is the WDW water parks! They have tons of fun slides!
