I saw this Groupon today when I was hunting for Vegas deals. Its not a hotel deal, its for a spa day, so I am not sure if this is the right place. Not sure if its a great deal, but it seems pretty good! They apparently did the same deal on Travelzoo last year and the reviews on Yelp were good...no one had any problems getting the deal. The travelzoo deal sold out at 711, and this one is at 500, so might not last too long.
