If you want some good BBQ and have a vehicle (it's a bit of a drive from the strip but absolutely worth it)!!!
Zipline down Fremont Street in downtown Vegas or just people watch because there will be lots to see lol - if you come bar hopping on Saturday you will get the Fremont St experience!
There are countless entertainment options on the Strip, from cirque de solei shows, shopping, food, an aquarium, etc. If you have any specific questions about any of them you can ask and if I went while I lived there I can let you know how it was!
