Check your email if you're AE; I just got a nice message from my personal ambassador:

Congratulations on another year as Ambassador Elite! I am very excited to have the opportunity to continue being your personal Ambassador in the new year, and appreciate you being amongst one of our most loyal members.

As a token of appreciation and special thank you for spending your year-end travels with us, I am sending you a $100 Marriott Bonvoy eGiftCard that can be used to make your stay a little more special – maybe a celebratory drink, a holiday dessert, or even a keepsake from the gift shop during your stay. Alternatively, you can save this for use on a future stay at any participating hotel if your plans change (see terms & conditions below).

Nice bonus to round out the year.
