I was recently in Vegas and played my usual games. MGM was running a tier credit bonus so I tried to hit a certain number in a day. I dropped as much in one day as I usually do on a whole trip and earned probably only 25% of the tier credits.
At this point it’s cheaper to just make Pearl or get the MGM card and pay for my rooms.
They said the point was to weed out non-gamblers, but they’ve weeded out this gambler. All programs devalue over time but this one was driven off a cliff.
