Stayed there Thurs, Fri and Sat night. Very crowded, obviously. The casino looks similar to the Bellagio. My room was on the 35th floor in the Resort Tower. Very tasteful decor, different than the Bellagio, however. Plasma TV in room, mini-bar, everything you would expect Wynn to have in his rooms.
Went to the spa and had a massage. Very nice area with 45 rooms for treatments. Tried out the Buffet. Was okay, but have had better in Las Vegas. Cafe was good but somewhat limited menu. Would I go back? Sure - they comped 100 percent of my stay.
