Chinese New Year!
I've been many a time, with many a soul, and I can't remember when I wasn't entertained. There are always thousands of fresh flowers, water elements, and unique colors and fixtures to gaze at.
The place is usually flooded with tourists, so don't expect a lot of space. But its vegas, so take a few family photos for people, smile, and enjoy it.
Beautiful, unique, and free. Need I really say more?
