The MGM Grand is one hotel and casino I have yet to see, although I keep telling myself I would see it on my next visit.
Plus I haven't seen the Wynn and now there's a near-duplicate of it called Encore, beside the Wynn.
Those are the three hotel casinos I would love to visit on my next trip to Vegas.
I have yet to see The Blue Man Group, other than on YouTube, and would like to see their performance one day.
