No, I avoid all casinos after dark on weekends unless a drawing or other promo unmistakably demands my presence, so I haven't encountered the mostly peaceful people.
M may not have reconfigured drastically during the interlude, but the gaming floor had already been thinned out pre-CoCo. From Gaming Control reports:
December 2012: 1593 slots, 57 table games, 10 poker tables
December 2019: 1120 slots, 40 table games, no poker
And they have continued to move stuff around. The 99.8% vp banks are unchanged, but many of the slots have been repositioned including the non-smoking area. They installed a bunch of plexiglass, including in high-limit vp.
