I believe that I may be disappointed...
If we accepted the information that Marriott provided at https://members.marriott.com/marriottrewards/
Then, as a "Lifetime Platinum" I should have been "Grandfathered into Lifetime Platinum Premier Elite" per the link information.
When I check my new status (as of Aug 19th), I am "only" a lifetime platinum, with "only" a 50% bonus.
Is this a devaluation ?
