STAY AWAY! If I could give negative stars I would. The worst experience I had in Vegas. A/c was broken when I arrived in the room. The walls are paper thin and you can hear everybody beside you and above.
The guy at the front desk tells me don't expect any wifi on the weekend because it will be busy (I should have turned around and ran). The bar is so sketchy you are better off buying some alcohol at the gas station and drinking it in your room.
I don't know if they make extra money but the front desk bills me extra for the weekend rate without my knowledge and I find out about it two weeks later on my credit card. They won't give me my money back and now I have to dispute these charges with my creditcard company. I moved to an airbnb after two nights and never looked back. Hopefully this motel will dies out with bad business practices and low life people that work there.
Btw the convention centre is not that close. It's at least 15min walk, you will see better hotels on the way and wish you spent a little extra to stay there.
