We saw the Cirque du Soleil show - "Ka" at the MGM Grand. It was amazing.
We tried the "CSI Experience" at the MGM Grand. Not sure I'd recommend it as a "must do" but it was fun.
We visited the Liberace Museum which was slated to be closed forever.
In his Liberace's early career, this gold jacket and ruffles was probably considered showy...
We always have to see the lions at the MGM Grand.
We happened to reach the piranha tank at feeding time. Dinner tonight (and every night probably) was live goldfish. For the squeamish, I won't show the actual feeding pics (they weren't very clear anyway).
The highlight of the trip (at least meal-wise) was dinner at the Top of the World restaurant at the top of the Stratosphere. The views and meals were spectacular.
