I'll go with the other poster, try to get 2 nights, one is hardly enough to get the feel of the resort. By the time you check in and settle, try the pool you'll be sleeping and headed out.
We were huge fans of the Poly, but prices ahve driven us away, unless a super code comes out, our next fav is WL. We prefer the MK resorts and like the lakes all around, plus the boats to FW. cheapest of the deluxes in that area is WL. Pol holds a special place for us, we've had many stays there and the beach and pool are fantastic, that was during DD college program discount days. Enjoy the resort and try not to make a huge fuss when you have to leave, deluxes get into your bones and is hard to shake.
