How about the actual terms and conditions themselves? How about public statements by the head of Marriott Loyalty Flueck or CEO Sorenson? How about official responses from Marriott as shared by the various points and loyalty bloggers?

I’ll also consider information from my Ambassador to be credible. I can’t speak for all Ambassadors, but I know mine does her due diligence.

I also generally consider information from the Lurkers to be credible.

I certainly don’t trust or find credible almost anyone here on FlyerTalk with few total posts making grand pronouncements or those with unnnamed “executive” sources or other unnamed hotel staff sources—too often from unidentified hotels.

Again, consider the source. Too many sources are worthless. Too many who report information on FlyerTalk do so in such a way as to make me pretty sure they heard what they want to hear (i.e. confirmation bias) and usually aren’t credible.
