With mlife, you really can't rely on the tier match. I am a Caesar's Diamond and Hyatt Globalist, and last week I went to the Player's Desk at the Aria and got my mlife status matched, so I got a gold card. Yet, online, it continued to show as Sapphire. Finally, a day or so, I asked the customer service at mlife when I could expect the gold match to show up (I'm now out of Vegas). They raised my status to Pearl. So, even if you show up and get the match, the system might not show you at the matched level.
My wife and I both matched CET to MLife ( previous Status Pearl) and we both show up as Gold online
I was also able to match our new Mlife Gold status to Hyatt Explorist a few days later which is what we really wanted, MLIFE gold is not much of an upgrade over Pearl as we have the credit card for check in line access.
Did you do the Wynn match while you were in Vegas.............we did and already received 3 night offers at Encore, no resort fees and $200 in free play.....we both played $20 at Wynn that day and had never been there before.
