Lifetime Titanium plus Diamond.
I have been staying at some Marriotts in the USA but also spread my usage to Hilton for the first time in a while during 2019. Treatment seems similar. With Diamond the points accrual rate is higher. With the fall promo and AMEX Aspire the average cent/point amount realized on redemption was higher for me by a factor of 27% comparing redemption value per dollar spent to acquire those points. Now without a good promotion its similar for Q1. Award stays at Hilton do not incur the resort fee which is an added bonus. I have enjoyed some good resorts in Hawaii, Arizona, and the Australian Gold Coast. I am not a road warrior any more but my Hilton stays booked for this yer are 3:1 vs Marriott. A good promotion and a good rate will switch me.
