What a joke this event is. It's a lot of delusional people calling themselves artists peddling their over priced trinkets on the streets. With the addition of several food trucks sprinkled throughout the various streets it basically makes this event a glamorized swap meet. Wow, how exciting! With so much to do in Vegas I don't understand why this attracts so many people. Try it once if you don't believe me but I'll never go back. Huge disappointment.
The good: park at the government center and catch the free shuttles to the event and back. They serve alcohol - you'll need it to trudge through the hour or two you're there. Most of the food trucks have decent food. There are a handful of actual artists who deserve to be paid for their gift.
