There is nothing WRONG with Poly. And the Bungalows out over the lake are picturesque (even if I could never afford to stay there), but I don't think they follow through very well at all on their theme. There are some SLIGHT Polynesian architectural touches in the construction, but that is about it. In other words, VERY LITTLE in the way of Polynesian culture or environment comes through in the Polynesian resort. And this applies to the entire resort. Add to that, Captain Cook's has horrible food. I love all kinds of foods, including American, Polynesian, Japanese, Chinese, Korean, Indian, Thai, and many more, so it doesn't bother me that they kind of try to do a Polynesian/Asian/American fusion in their food. I just think they mostly fail at it. On the other hand, I do like Ohana and Kona Cafe. The monorail is fun, but is not a very efficient method of transportation, really. It takes far too long to make the trip around the Seven Seas Lagoon, and also over to Epcot, so I'm not that impressed with Poly being a Monorail resort. I guess that if I am staying in a Resort called The Polynesian, I want to FEEL like I am in Polynesia, in a Tropical Island Paradise. I want to be reminded of it every day by much more than just the name and then a few superficial touches. I want the resort itself to be MEMORABLE in ways that it is not. AKL does an amazing amazing job of handling it's animals and African theme. Wilderness Lodge could be right out of Yellowstone Park or one of the old Redwood lodges. Beach Club doesn't really have much beach, though it does have Stormalong Bay. Boardwalk is just what it says it is. Even Bay Lake Tower, which is modernistic and different from other Disney Resorts keeps to its theme and has amazing views. Poly just comes out way down the list, and it is mostly a failure of landscaping and atmosphere.
I do own 325
DVC points at Poly, so I think I am not 'prejudiced' against it. Given a choice of staying at French Quarter or Poly, I prefer French Quarter.
