I have zero chance of achieving this, but I am young and jobs change and so may travel needs and brand coverage in my targetted geographis.
I am pleased with 1000 paid nights nonetheless - it avoids diluting diamond status further. Theoretically, with about 25 paid stays a year, Lifetime Diamond would appear just as I retire
(I guess the world will look very different then, so I will not aim for that at this stage
)
