I have a lot of issues with 2018....same emails as above. I knew I would lose 7* status Feb 1. Didn't earn enough tier credits last year. However, on a January trip to Caesars LV, I earned 30K Tier credits over 3 days. Feb 1, I dropped to Platinum. Spoke to TR, my host etc. No one can figure it out or help-but all agree I should be Diamond. They told me to visit TR on my next trip-which is Thursday. I'll guess I have to do that, but right now my offers are wrong and I'll have to pay additional fees at CP if it's not fixed.

Might look at Mlife as I like Bellagio, MGM National Harbor and Borgata.
