I go to vegas twice a year and have never been to this area. So finally on my recent trip, my friends convinced me to give it a try.
The feeling I got when we arrived there was more like of a fair. The electric light show overhead was totally awesome. They were playing Bon Jovi the entire time and I loved it. They also have stage for live bands.
Lots of souveiner stores also. Their quality of course is not as great as the ones at the strip hotel's gift shops, but if you're looking for some simple stuff like key chains, this is the place to buy them. Its 3-4x cheaper. Speaking of cheaper, my friends told me about their cheap drinks, though I didn't get to try it for myself.
Oh yeah, they have zipline as well.
This place is not as extravagant as the strip but it's worth visiting once for a change of scenery.
