This is what I got from Harrah's as an e-mail reply to my inquiry about the new DIAD rules.
I have a friend who is going to LV over Thanksgiving week-end and he asked me about
DIAD.
With the new Diamond in a Day requirements, if you earn your Diamond status Jan-Nov
you will have that status until Mar. of the following year, if you earn Diamond status in
Dec. you will have that status for the entire next year until Mar. of the year after. So if you
earned DIAD status while you are here for Thanksgiving 2006 you will keep your status
until March of 2007. If you have any further questions please feel free to contact me.
