I think this is something new for current users. I've had the
regular Marriott Visa Signature since 2003, and at that time I only received 15,000 bonus points with my first purchase. Two years ago, I applied for and received the Marriott Visa
Premier card with all its benefits.
About 3-4 weeks ago, I received a flyer in the mail about the
regular Visa Signature, that I already have, being upgraded for me to receive 10 free nights towards my account. However, I am waiting to see when the Visa Premier's 15 nights are credited.
