Flamingo, hmm?? Have to try there. Usually when I'm on that side of the road center strip I play Harrah's (or back in the day Oriental Palace). I like MGM too, good semi-soft action. Gotta try Hard Rock, it's supposed to be soft with drunks after midnight. Also, I hate waiting and waiting for a seat in my games, which ruins it at my favorite Bellagio and many other places.
Oh, and on Uber, they aren't all good or safe drivers. Had one picked me up Stratosphere, was supposed to take me to Orleans but went to wrong Boyd casino. Then he raised a stink and kicked me out of his car; definitely high on something. Rider beware, and Uber "management" rarely gives you any satisfaction or gets involved in individual problems.
I'll be there a week from now, so ready and eager ... And I like downtown hotels who have no resort fee and reasonable prices, like Four Queens or Californian. Fremont music/noise shuts down between 1:15 and 1:30am, so one can still get some sleep easily. Buses get you down the Strip when you want to go; buy a day or three-day pass, beats driving!
