This has been discussed often here:
Trying to understand the Courtyard business model
I feel like there was an epic thread at like 20 pages where people just mocked Courtyard, but I cant find it so maybe its not as epic as I remember.
But yeah, since the beginning of Flyertalk, people be like “LOL ... Courtyard” and Marriott be all like “we make buckets of money every day, we know what we are doing”
So, in the end? Whats the point of Courtyard? To make money for Marriott and shareholders. Apparently it works, otherwise there would be no Courtyards.
