No, I matched my Caesar's Diamond to mlife gold, but no other matches. I did it in person at the Aria, and then I went and played $1k at the Blackjack table (also which did not show up online). No decent offers now that I've been back home for a week.
I think you missed out not doing the Wynn match, it's far better than MLIFE Gold which basically gives you nothing in Vegas you can't get by simply signing up for the Credit Card.
The Value in the Mlife Gold Match for us was the Hyatt Explorist status.
If you are back in Vegas before 9/1 I suggest taking advantage of the Wynn offer.
All of my play from last trip in June is showing up on my June win/loss statement
I wonder if somehow your mlife # is not correct, have you compered your account # when you log in to the # on your new old card ?
