Vdara is a nice choice if you're looking to stay at a non-gaming hotel. The entire property is non-smoking and you get a slight floral scent as you enter the hotel.
I stayed here on two separate occasions in the same week. I packed once for both trips and just left my luggage with the bell desk in between my stays. I flew back a day later and retrieved my luggage without any issue.
The rooms come with, at minimum, a mini-fridge. Couches are pull-outs. The rooms are pretty spacious.
If you plan on clubbing, it's a short walk to Marquee. This property neighbors Aria and the Cosmo so you're not too far from some entertainment.
