Just received my Megabonus offer in the "snail" mail today (Earn 1 free night at a Cat 1-4 hotel after every second paid stay...). However, the mailer includes pictures and names of 4 Marriott properties with the words "start dreaming, start indulging, start unwinding, start discovering" which (in my opinion) would lead you to think you can use your free nights at these properties. However, I checked, and only one of the 4 properties featured in the mailer is a Cat 1-4 hotel (Beijing Marriott Hotel Northeast). Two of the 4 (JW Marriott Phuket and Courtyard Rome Central Park Italy) are Cat 6 properties, and the other one (Waikiki Edition) is not even a Marriott branded property anymore. Just my opinion, but I think the marketing materials should match what's actually being offered.
