I may be stating the obvious here, but at some point, is it worth it? I remember a campaign back in 1999 (yes, I’m that old), where you got bonus points per stay (not per night), which led to some unnatural acts all over Manhattan for people on weekly projects. Half the bonus points didn’t post, and there was the endless chain of emails to customer care. These days, for chain based bonuses (ie run by corporate), I find the accounting to be surprisingly accurate. If something is down to the individual property, I would view it more as a sport…

OTOH back then at least 25% of my shuttle flights also never posted, so I’m ok with blaming the “systems of that era” for most of this stuff. These days, despite the gargantuan challenge of harmonizing the systems of umpteen chains, Marriott does pretty well (apart from their website). If only the human side of it had improved as much…
