I signed up on 5/6 January not sure the exact date and I had my nights credited on activation so stacking my Amex I have 30 nights and haven’t stayed anywhere so that’s great.
I expect the majority of my stays in hotels in Feb and April to be covered by the (hopefully) double nights promo so I should renew Titanium before summer.
And I also won 100,000 points on the raffle they are doing for their sweepstakes for new entries! Which is super helpful for me to book 5 nights in the Maldives at the end of the year.
