I loved Vegas too and I don't do any of those things either. Well, I played a little slot machine but that was it.
My favorite casino/hotel was New York, New York because well, it reminded me of home and because upstairs they had the arcade games and electric crazy cars. There's a roller coaster (which I didn't peruse). The Statue of Liberty replica! The 9/11 memorial is touching.
I also loved going to live shows in Vegas (I recall seeing Danny Gans' show (who is sadly no longer with us either). My favorite band Chicago! I saw Barry Manilow! I saw an incredible Beatles tribute band. I liked looking at the Sigfried and Roy lions. Just walking through the huge, glitzy, fancy schmancy casino's is fun. Or just lounging by the pool (well, I hated wearing a bathing suit in public). There's the lazy river at the Bellagio I think! The dancing fountain at the Bellagio! Beautiful!
Oh, and I was fascinated with the winding escalators at the Wynn...lol.
Shopping...don't forget the shopping. If you have money (which I didn't...heh) you can drop thousands there on shopping.
Last time I was there was 2005, I think. I wish I could afford to return.
There's lots to do and see in Vegas that is wholesome. But I would like to know specifically what Michael liked to do there.
