Stubtify, really admire your dedication on this. You may want to invest a little time in mitigating your risk by following the misc. hotel promotions posted around FT.

For example, Marriott just finished a contest where many of us won at least 1000 points for very little effort.

Priority Club and Hilton are part of TopGuest, relatively easy way to earn 50 points/day if you're in the right geography.

Lots of little opportunities here and there to earn in hotel programs without stays.
