I think in terms of the resort itself, I do prefer AKL over Poly, but the location of the Poly is clearly better. Both are beautifully and uniquely themed, but to me, all of those animals just make AKL unbeatable.
Honestly, if we're talking ANY deluxe, we stayed at the Boardwalk Inn for our wedding night and a few nights after and really loved it. The Epcot resorts have the best location, imo, since everything is so walkable and World Showcase is a wonderful evening destination. And Boardwalk Inn is a really nice hotel... beautifully done, with an upscale feel.
I'm not too crazy about POR for a special occasion, if you have the option of a deluxe, because I don't think Disney carries the theming to the inside of the rooms as well as they do in the deluxes. Beautiful grounds, but very generic room that felt like a nice motel room. For a moderate, we liked CSR better! Actually, I also liked POFQ better, but probably not for a special occasion. I haven't stayed at CBR since right after it opened.
