Just my opinion, but in my view overcrowding at the Poly pools is due more to the smallish size of both pools and pool decks relative to the size/number of guests at the resort. Sure, you're going to get some non-guests that break the rules and find their way in, follow behind someone, etc - but I don't think that's the sole cause for it feeling/being crowded. Maybe a small piece of it, but not that main contributing factor.
The total SF of water and deck area at Poly is just smaller overall than some other resorts, so it can feel very crowded at times.
When are you going? The only time I've felt the "people soup" problem was last July, late afternoon. That was the only time where I was like "this is no fun, let's get out."
