One of the nice things about where I work is that it involves occasional work trips to our parent organization in Vegas. Last time I saw three Cirque du Soleil shows and a body building competition. I have another trip in a couple weeks, and I'm looking at a show called Awakening at the Wynn, "the seance show" at Lost Spirits Distillery, and a Golden Knights hockey game. Good chance I'll have another trip over New Year's. Maybe some wonderful soul(s) here could throw out some other recommendations.
