Wow, you'd think they took out the totems, the fire place and replaced all the wooden beams with steel. Having stayed in the WL quite a few times, though I do love the theme, it's not like this one water feature is what makes the place. It's a small element, which when combined with things like the totem poles and the rest of the lobby decor, makes for a wonderful overall look. But make no mistake, it's not as if this water feature is on par in scale to say the one being removed from the Poly.
I would gather a large number of visitors won't notice immediately the construction walls off in the corner by the elevators for a while after entering the lobby. Sure, it's disappointing, but nothing worth getting worked up about and nothing any resort or hotel chain would discount a room over.
Heck, I just stayed in a hotel in Santa Fe that had wonderful in room fireplaces that were stocked with a beautiful pinon to burn last year. This year, I got a Duraflame log. Hardly the ambiance of real wood. I politely complained for fun and profit and was not granted any sort of discount. Just an "Oh, I'm sorry, our usual wood supplier was unavailable this weekend."
