Polynesian. Been there three times and going again in May.
Great theme. They really pull this off. The landscaping has really filled in over the years. Walk down the pathways at night and, with the lush gardens, the torches and the music, you really feel like you're somewhere in Polynesia (until you get the bill;

then you realize you're in Disney :lol: )
Great crowd. Whether you are going as a couple or a family of 5, you will fit right in. My wife and I went there for our honeymoon. We felt like the place was made for couples. But the resort is very, very kid-friendly too. I stayed there twice when I was a kid. There is a lot to do and the place is pretty rustic so it's built for kids. That's my one knock on the GF. I feel like they would kick my kids out for breaking things or being too loud.
Great food. Kona Cafe and Ohana are great. Captain Cook's is as good a fast food place as there is on property (as long as you are not in a hurry because they can be slow).
Great location. This is hard to beat if you will be spending a lot of time at MK. You have the monorail running right through the resort, friendships to MK, and the TTC is a short walk away.
Great price. Ok, not quite. . . . Ok, not at all.

If you have to take price and value into the equation, then I move the Poly down a little. When you stay there, you really want a lagoon view. The garden views are great and much better than your average garden/pool views. But IMHO, nothing beats seeing the Castle from your window. But you pay for it and, unfortunately, it's too expensive.
BTW, I think I read somewhere that it is rude/insulting to call it the Poly. Anyone ever hear this?
Anyway, just in case you missed it, I love the Poly and that's where my vote goes.
