Marriott made it harder and harder to use your points. Some readers thought they just wanted to make it difficult to use your points so that you wouldn’t but that isn’t actually true. The people at Marriott worried about fraud (especially after major data breaches at the chain) gained the upper hand over anyone that cared about the loyalty of their best customers trying to use their points.
The last thing I ever want when redeeming points for my wife’s travel, though, is worrying over whether or not she’ll be able to check in!
