Got my hard copy mailer today notifying me of the changes (in addition to the email a few days ago).
Noticed that the benefit for the complimentary 4th night will be modifying as well:
The International Complimentary Night Hotels and Resorts Program Terms and Conditions are effective starting on October 19, 2014:
You will enjoy a complimentary fourth night with no black-out dates, when you book four consecutive nights at any hotel booked by a personal travel advisor designated by MasterCard (the "designated travel advisor" is Carlson Wagonlit Travel). Bookings made through other methods such as, travel agents, websites or directly with a hotel will not qualify.
The terms states the complimentary fourth night will be valid with ANY hotel booked via the personal travel advisor and there is no limit to how many times you can use this benefit.
I'm a bit skeptical on the ANY hotel part of it; previously the benefit only applied to the Luxury Hotels Collection from World Elite Mastercard...
Anyone have any additional details?
