I'm definitely not certain of the changes, but from what I have seen of the released design plans and from experiencing in person what is indeed being worked on, I can say that the Polynesian we all know and love will still be there. And in response to you and what kkocka said, large portions of the lobby like the charming stairwells, the hallways, the restaurants, and all the art work appear to be staying. It is a shame that the waterfall was taken away but there is so much more to still cherish. All of the wonderful walkways will still be there, the torchlights, the main buildings and the overall design and aesthetic have been largely unchanged since 1971. I am still weary, but I remain optimistic. Because the Poly is much more invaluable to WDW property than most people realize. I'm sure that factored in to the decision to get all the work done at once.
