We've done quite a few stays at the Poly, back when room rates were less and discounts were bigger. What we liked was the atmosphere, very quiet and serene resort. What's is different, pool is small and tends to be crowded, less lounging and seating in pool area, individual longhouses means going outside and long walks to food courst and monorail but the kicker is the price, too high.
AKL, stayed there only once, didn't care for the layout, long walks to the lobby, pool and food court and to go anywhere it's a bus.
WL, our favorite, easy to snag a good rate even with
AAA. Pool area is huge, alot of seating, chaises and tables though others feel the pool is small. The pool is "U" shaped and we never had any problems with swimming or seats. Last 10 stays have been there. Resort is all under one roof and no matter where you're at it's a short walk to the food court. The boat to the MK is fast and relaxing and you can take a boat to FW or CR to gain access to the monorail. EWP each night is a nice touch, does have a marina and beach and the pool area has 2 hot tubs if that's your bag.
We pick for location, especially for the MK, like being on the water with both lakes it's just a different feeling. But bottom line, though the rooms are alittle smaller its the price. Poly too expensive, AKL to remote and WL is priced right and convenient.
