I'm sure many can make the program work for them. It doesn't sound like a terrible program. But the model of 'give us cash now, and try to earn it back later' is just not for me.
I seldom stay at Accor properties and I have status in three other hotel programs that I'd favor first, so it would require a big change in habits to move towards Accor and benefit from this program. And their marketing is most definitely making them even less preferred...
