Well i was just sent it!
Same with a Hyatt Gold, then the Accor Platinum, which i renewed this yr as stayed over 35 nights.
It depends on the profile in the FB system, whether you get some of these offers or not i believe, if they have a prospect with yr travel patterns of obtaining business from you.
I was a Flying Dutchman Gold for many years, always have had the hotel cards sent, through their mutual marketing, but always through KLM mails. I have a a draw full of Hotel memberships, its like a pack of cards round the world!
