I agree that the Poly is romantic and beautiful!! The atmosphere is so tropical and lush.
I have been wanting to stay there for years, so on our last trip we went over and asked to see a room (we're going back 3/12). The were extremely welcoming and immediately had someone show us to a room....
I was a little disappointed. The room was maybe 8 to 10 feet longer then a moderate resort, but the decor and the furniture was average. The windows were either tinted or very dated looking, and since it was a standard room, it looked over a black tarp/awning and into another building.
My other problem with the room was the bathroom. We have three children, so when we are getting ready to head out, I love the bathroom areas that have the sink and mirror outside the bathroom, with a seperate room for the shower and toilet. This way, everyone else can be brushing their teeth and getting ready, while one person showers privately. For you, it will just be two of you, so that won't be an issue, but for a family (especially with older children), that would never work.
That said, we spent three nights at the Polynesian for dinner (the Kona and Ohana-and we did request a window seat so we could see the fireworks while we had dinner) because it really is a beautiful resort. I just expected the rooms to be brighter and fresher.
Good Luck and congratulations!! I imagine you'll be blissful wherever you stay on your honeymoon!!
