I would not trust someone on the phone stating that MVCI owners will still be able to redeem Travel Packages under the current points structure after January 14. The messages that Marriott has posted on FlyerTalk and on its website and on the Marriott blog about the new points structure for Travel Packages seem clear.
Further evidence is in what you were told - that they weren't announcing it "because others will get mad." How long do you think that would be kept a secret if, in fact, Marriott did enact a two-tier points requirement for Travel Packages? Not long, for sure! And the people who would have to use the more expensive tier would be the business hotel guests, the people who really make the big profits for Marriott. I can’t see it.
Further still, the rep said that he had researched the issue, but didn't volunteer that he had confirmed his research with anyone. One person countering everything that has been carefully worded in the announced program and by the Marriott rep on FlyerTalk? I can’t see it.
Bottom line: I don't believe this news for a second. There has been much misinformation generated verbally about the new points structure. This could easily be more of the same.
If you rely on this "news" in your Reward planning, be sure to remember that you were warned.
