As suggested by gatorlitigator, here's a discussion thread where those striving for Marriott LTP by 12/31/18 can post their progress.
As we've learned since the April announcement of the loyalty program merge, members who achieve the legacy Marriott LTP (2M LT points and 750 LT nights) by the end or the year will grandfathered into the soon-to-be-unattainable Lifetime Platinum Premier (LTPP).
In the discussion Lifetime Gold, a stop on the road to LTP (or the end of the line), Gatorlitigator proposed a friendly race to the LTP finish line. In reality the race is not against other Insiders, but against the clock. Time runs out on December 31, 2018.
Between now and the end of the year, anyone working toward this goal can post their progress as a comment on this post. The suggestion was to track progress monthly, so on or around the 1st of each month, those wishing to provide updates should list their current LT nights and LT points totals. If you want to provide a screenshot as well, go ahead (for details on how to find LT points on Marriott.com, check out https://insiders.marriottrewards.com/thread/54252#comment-248549), though that isn't necessary.
Please post those two numbers, however, don't hesitate to add more detail on what you did over the last month or what you're planning for the next month (or the rest of the year) if you think others might find that information helpful.
Folks working to reach any other statuses, say LTG, can also post updates if they wish.
Remember, this is not a race to see who gets there first. It's a way to encourage each others to make it to the finish line before the end of the year.
Good luck to everyone making the attempt.
