Just got back from Vegas. 4 nights at Vdara. Very nice hotel, no casino and no smoking within the hotel. Aria is just a 2 minute walk across the roundabout! Only complaint is its a bit off strip so you gotta walk about 15 minutes through Bellagio (or take the Aria Train from Monte Carlo).
Got a smoking deal (booked in May) for this trip. $399 per person from Bellingham flying Allegiant including one free show.
Bad ass view from my hotel room, 49th floor
