Well, let's see if this actually works...
I personally find it bothersome to have a newspaper at my door everyday, so I checked the "No newspaper" in my profile a while back. Yet I still get it every morning...
Asking the front desk to stop the delivery makes it stop though - but then what is the point of the profile in the first instance?

So if Marriott properties cannot manage NOT delivering a newspaper based on profile preferences, no wonder they have issues honoring the actual prefered choice...
