UFO!!
That's how I always identify this mall. It's huge though I've never actually walked the whole thing. I've bought a few things from stores easily accessed from its many doors but going into the heart of the mall a couple of times. I remember seeing a fashion show of sorts once which was all right.
Finding your way out of there wasn't too troublesome if you want to grab a cab. Though you might be in for some frustration if your cabbie decides even though there are a gazillion cars and big shuttles in front of him, HE can STILL get by. Oh yes.
I find it's best to visit this mall after eating at the Wynn buffet. Time to work off some calories!
