It looks nice. Just nice. As good as you could want it to look considering the lobby's defining feature was taken out, and replaced with furniture and lighting.
@Incomudro asked an interesting question about whether we would like the reverse, and if after having a lobby like this, whether we would like having it all replaced by a huge fountain. I'm not sure I know the answer to that. I think scaling the fountain down or breaking it up into smaller segments would have been an understandable move, allowing further passage through the lobby while still having some of that "wow" factor, and maintaining the lush tropical feel. As it is, it looks like they tried to scale the Wilderness or DAK lodge concepts to the much smaller space of the Poly lobby, and without the extravagant theming of the lodges' architecture.
It sounds like they may be attempting to relocate the lush landscaping/fountain concept to the outside. I'll hold out to see if that's true, and I'll be somewhat happier if it is.
