I'm definitely one of those who will take full advantage of my newly minted Diamond status. 162 total nights in hotels in 2015 (109 with SPG, 47 with Hilton and 6 with Ritz/Marriott). Over 50 of those nights will now go to Hyatt as I'm reasonably sure Marriott will not be keeping SPG Ambassador status. I only wish Hyatt would introduce a 100 night status including a Courtesy Card (hey a guy can dream).
