Years ago the RIO was a fantastic property. Friendly dealers, nice atmosphere, great restaurants. Then it was Harrahtized. As this was the first casualty of Harrahs it took a while to destroy the place. Slowly changes were made that made us wonder why we kept going back there. The table games in the Masquerade area were removed, more slots with poor odds were added. Then the other table area was shrunk.
Then about three years ago they replaced all of the friendly efficient and beautiful cocktail waitresses with bevertainers. Every 15 minutes or so the music would blare and some poor girl would stand on a pedestal to dance and sing. Really ruined the casino atmosphere. We have not been back since.
I am sure that Harrah's has learned how to expedite this demize of their newly obtained properties. Expect the decline in service to continue.
In comparison, the mob did a fantastic job of running Las Vegas. Hasn't been the same since they moved to the background.
