First year it was just the mountain, music and trees. They brought it back a second year and added the bellagio style fountains. Of course not ad awesome as the bellagio.. only downside is they made the fountain area all black to hide the fountains. Looks bad during the day compared to before the change. But overall worthwhile change.
I heard someone else is getting a cirque show this year... maybe KI? ours is really good. 10 times better than the typical amusement park show.
