No invite for me.
I hit Lifetime Platinum a few years ago, staying at Marriotts pretty exclusively for the past 15 years. PP for several years, then dropped to P, then back up to PP last year. Current stats:
139 nights so far in 2016 (with 4/week booked through the end of the year).
579,425 points (just blew through 720k with 4 x 4-nt stays in Times Square).
I don't see where I can find my lifetime stats, but by my records I've got over 1,400 nights. In 2015 I've spent $700-$800/week with Marriott pretty consistently, and am on track for the same or higher this year.
A coworker with very similar spend/stay pattern & history was invited, I was not. He also mentioned a new promo that sounded similar to a megabonus, but it must be targeted as I didn't qualify for that either.
The only difference between us that I can see is that I pre-book 6+ months worth of stays in advance, and he rolls with only a couple weeks out at a time, booking as he goes. I guess they figured with that many bookings, they don't need to incentivize me.
