We haven't been there yet (going in April), but the pool at The Fountains gets great reviews. It's big with various "lobes", one of which is zero entry and has water play stuff, another has a couple of big slides. They've also got an indoor/outdoor pool. Most of their units are 2 BR/2Ba, officially sleep six (one king, two doubles and a sofa bed), and have their own washer/dryer and a full kitchen. Depending on who you ask (I suspect depending on the time of year) it's a 10 or 20 minutes drive to the parks.
