The ONE and the ONLY place I stay at when I visit Vegas, and I come often.  The hotel offers nothing but palatial suites, all of which come with sunken living rooms with plasma TVs and bathrooms to rival the size of a typical NY city apartment.  The amenities at the hotel are the best in show.  Canyon Ranch has an awesome gym, and every massage I've gotten there has ranked as one of the best ever.  The pools there are also some of the best.  The luxe tower of the Venetian- as if the regular tower isn't luxe enough- is called the Venezia.  The pool at that tower is remarkably phat.  You feel like Italian royalty being there.  Tao, which is also at the Venetian, is by far one of the most scorching hot spots Vegas has to offer.  I've been to Vegas some 10 times, and I can easily spend the whole time at the Venetian.
