Why does Marriott continue to use Chase for their Visa cards? As a road warrior, attempting to keep Chase informed of my locations daily is a pain and usually a wasted effort. And even if I am in an area for several days, they flag my card after several transaction have cleared. Do they call to check a "suspicious" transaction, absolutely after waiting an hour or so. Since this appears to be an ongoing problem with Marriott no addressing it with Chase, I may have to seek other lodging arrangements. Putting up with sub-par customer service may be acceptable for someone on the road 3-4 months of the year, but for those of use who spend 95% of the year on the road, dealing with Chase is not worth the effort.
