You will need a jacket so that you can flap it around to create a breeze. That's about it.

You won't need one for going outside, day or night. But you might bring something very light for indoors.

You have packed already ? is that not what the night before is for :)

I don't find the casinos to be as chilly as they used to be for the most part. But if you're the type that gets cold easily, a light sweater or jacket is a good just in case item to throw in your bag.

I was there a couple of weeks ago and did not need a jacket in the casinos, restaurants or show. In fact I couldn't imagine even carrying one. A light shawl that can be either be folded up and carried in your purse or tied to it if it won't fit inside as an option. There if you need it and hands free if you don't.

I think they keep the casinos about 70F and to me that is chilly. I always take a jacket, sweater, or I try to layer just to be safe. I really don't like being chilly when I am gambling.

I just got back and while I didn't need one at all in the casinos or anything, I would have loved a sweater to put on during all the shows I saw. Carrot Top and Michael Jackson One were REALLY cold inside.

Thx all, I even find our local shopping mall freezing after a few hours.....packin a cardy then & yes red I have started to pack! I'm excited, forgive me :)

As a person who ice fishes I learned its always better to have extra clothes and not use them then to need extra clothes and not have them

That being said I coming to vegas first week if September and it's always around 100 degrees so I won't be bringing anything but shorts and swimming trunks, so I will be there the same time as you and honestly no jacket needed
