So I was just at Mirage for a week, made some serious progress on tier credits, but noticed that after I got home, my tier credits dropped! I know when I went to see a host Monday afternoon, she said I was 29,000 away from Platinum. Now on the website it says I'm 41,908 away from Platinum! Is that typical for the tier points to go down? I feel like I'm getting screwed!

Another question - if I become Platinum on my next trip (most likely this summer) then will the Platinum benefits be only good til September 30? I know the tier resets October 1st, but will I be Platinum all next year as well? If it's the former, and let's say I don't get to Platinum til August, then it's not really worth it to only be Platinum for a month or so...

Thanks for the help!
