Thanks for the links!
Now I don't want to sound greedy, but since I am a (sort of) loyal Hyatt and Hilton customer: Does anybody know of a promotion where you get comped to status with those two chains? I checked their respective boards already and there seems to be no current promotion. Has anybody ever tried to 'just' call or email them and ask for comped status?
Thank you for your answer to this slightly "off-topic" question.
