I mean yes but those were very different beasts... Turkish gave folks nearly 5 months to fly to 6 continents and SAS gave folks 3 and a bit months to fly 15 airlines. I think that's very different to 38 brands in 75 days of which quite a few are difficult to find and not to mention, marriott points are noticeably less valuable than airline miles.

What would make it so good is people would try and they'd get to about 33-35 and then figure out they have to catch a flight to africa or america or asia to get the last few and probably throw the towel in when they notice they've only got a week or two left until it's over. So your pool of people that could potentially complete this are unemployed wealthy guests that have unlimited time to travel who probably have better things to do than completely a 75 day challenge to get some points. So yeah, I think it would be a marketing win because sure, you'd get a few folks but then you'd also get a bunch of youtubers/social media folks probably.
