No shows whatsoever, not the comedians, not the magicians, not the blue men, not Cirque du Soleil , not the topless girls??? You should do a show. I've seen Lance Burton and Blue Man and a couple of the topless revues and Siegfried and Roy before they stopped performing. If you gamble you have a chance at getting things comped from buffets to rooms to shows. You can do some aerial tours of the area. It might be hard to fit in the Grand Canyon in 3 days but they offer aerial tours of it. There's all kinds of museums, concerts (check what's at Hard Rock). There's the art galleries like in Bellagio. There's gondola ride inside the Venetian. There's plenty of fine dining for a nice romantic dinner. There's lots of shopping. You can rent a high end sports car.
