Well, what do you know!! I've been through Lifetime Silver, Gold, and Platinum over the last 8 years but have never received a whisper from Marriott. I hit the Lifetime Titanium numbers prior to the category being established.
Today, the mailman delivered my Lifetime kit. Very nice packaging and a metal lifetime card. It's heavy metal!!!! I'm not sure I can get through TSA with this in my pocket! I may need a new belt to hold my pants up from the increased weight!
