NOTE: Members who reach 750 nights and 10 years at Platinum by December 31, 2018, will be grandfathered into Lifetime Platinum Premier Elite status (notified January 2019). In addition, members that achieve Marriott Rewards Lifetime Platinum under the legacy requirements by year end will also be grandfathered into Lifetime Platinum Premier Elite status. And don’t forget that we’ll combine Lifetime activity across both Rewards and SPG toward qualification when members combine accounts. Beginning in 2019, qualification into Lifetime Platinum Premier Elite status will not be available. See FAQs for details.
I think she was referring to the above, so I am already lifetime plat by year end, so wouldn't that mean come 2019, "also grandfathered in"
