I'm not sure of any woodworking type places to go, but people are offering restaurants and other activities so I might as well join in.
As mentioned, Cirque shows are some of the best shows I've ever seen. I've been to almost all of them. "O" and the Beatle's themed "Love" are my favorite. "Le Reve" at the Wynn Resort is really good as well although it technically isn't a Cirque brand.
The best Steakhouse I have ever eaten is Strip Steak in Mandalay Bay. Pricey but worth it for the rare occasion.
As mentioned, In N Out Burger is a fast food burger that is amazing for what it is, a fast food place. Has a huge cult following but is really good and worth trying and incredibly cheap. Around $5-6 for a meal.
Vegas has incredible architecture in huge buildings with a ton of details and high end finishes if you are going to the nicer places on the strip. As a builder, I enjoy walking through the hotels as much as anything.
Good luck at your event. Enjoy the trip, it is a fun place to visit.
