Without even mentioning the problems they've had with the waterfall, one of the biggest complaints about the Poly has been about its 'dated' lobby and how it needed to be modernized. And now that they give a rendering of a more modern, open design people dislike it.
As Tikiman can tell you, and as I know from visits starting in the 1970's, the Poly lobby and entrance have changed several times over the years. This is just another change but boy people hate change. Me, in this case I like the change to something more open and glad they are doing something about the water feature that had had so many problems and already been cut back.
